In today’s video, we’re going to be discussing stride dynamics in the high-level throw. In order to do that, we’re going to use Zach Greinke as our pro model and then show a few other amateur variations, while going into some detail on how strength and mobility play into the equation for developing this powerful stride.
This is important to understand because a lot of the other qualities we look for in a high-level throw – such as achieving efficient “extension” at release, repeating the delivery, and executing our deceleration pattern consistently in an effort to reduce stress – all rely on having a stable stride pattern. In order to understand how this works, let’s take a look at some of the components that make up Greinke’s stride:
As you can see, one of the defining features of Greinke’s stride is the efficient action of his back leg and hip directing the pelvis down the target line early to set the direction and momentum for the stride. The way this is achieved is often overlooked and ultimately results in “offline” or unstable landings.
If you’ll notice the move that Greinke is making here is a posterior weight shift where he actually pushes his hips back in the delivery by hinging at the hip and not drifting his knee forward over his toes like most amateurs do. By engaging his posterior chain in this manner and not relying simply on his front leg to swing him into landing, he’s able to create a more balanced stride phase that unfolds in a more rhythmic manner, using the lead leg as a counter-balance to the delivery and not the primary power source.
For those familiar with the strength & conditioning world, I typically like to relate it to the initial movement of a one-legged squat to feel the glute and hamstring engagement and then a lateral lunge to stay engaged in the adductors for control of the pelvis. The lead leg action is ultimately just a relaxed extension to counter the posterior weight shift and then a swivel in the hip socket to align the foot for landing.
The effect of engaging the rear leg’s posterior chain allows us to create both extension and rotation out of the back-side, which is important for maintaining the direction of our force into the ground at landing. If we can’t control the force of our action into the ground, we won’t be able to stabilize our landing appropriately, which has ramifications up the chain into our pelvis positioning, core stability and ultimately into our hand positioning on the ball at release.
If we’re trying to create a level of “extension” at release and maintain our leverage on the ball to throw it with angle, we need to take ownership of our pelvis positioning. If we don’t actively control the pelvis movement into landing, we’re going to have a hard time centering the head of the lead leg in the hip socket, and in turn, accepting the ground reaction force that we’re trying to create. This happens when we lose the tension of our back hip too early, because we swung our lead leg out as the power source and “chased it” into landing. This means we won’t have control of the pelvis upon landing and we’ll be unable to properly pressurize the front leg to keep leverage in the delivery.
This pelvis leverage is essential in making sure we can keep our core stable and allow it to translate the thoracic region forward, instead of rely on it to create motion, which isn’t the primary role of the lumbar region. We want the “core” to simply transfer the energy we created from the lower half efficiently. If we can do that, we allow ourselves to accelerate on a longer line to release, because our path of deceleration is set up to be fully accepted on the front hip’s internal rotation and flexion. If the pelvis is too flat, and relies purely on rotation and not flexion, our line of deceleration becomes much shorter and forces us to handle more of the stress in our throwing arm, which isn’t ideal.
A good example of how both length in the adductors and strength in the posterior chain helped an athlete achieve a more athletic and powerful stride can be seen here. The first clip is a video of a 17 yr old LHP, who was 6’4” 180lbs, and 82-84 at the time of the video:
Notice how his stride pattern is very limited not only in his length toward home, but in its inefficient direction and its ability to allow for a full finish to protect the arm. As you can see, this athlete struggled to get a posterior weight shift out of his gather position, drifted into a closed stride position, and then had too flat of a pelvis position to achieve a proper flexed hip position. As a result, he runs out of lateral rotation in the lead hip and the finish buckles on him. This could be a result of many things, including limited adductor mobility, poor single leg stability, weakness of the anterior or rotary core, etc. Candidly, though, you usually see all these things in untrained pitchers!
Fortunately, this same athlete took it upon himself to devote some quality time to making himself a better athlete, getting stronger, and gaining awareness for the movements the high level delivery was asking of him – and he’s now turned himself into a legitimate prospect. In this more recent video, the athlete is 20yrs old now, 6’5” 215lbs, and 88-91mph, topping at 92mph:
By no means is this athlete a finished product, but you can see where the added strength, mobility, and movement awareness allows him to get into a deeper hip-hinge position, ride out of the stride longer, and certainly take the finish deeper to allow for a longer line of deceleration. The next step for this athlete will be continuing to work on his single-leg stability, as you can see a slight wobble in the landing and a touch of misdirection, but certainly leaps and bounds ahead of where he was three years prior.
To give you an example of where this stride pattern can go, here is an example of one of our more accomplished athletes, Tyler Beede, who was the 14th overall pick in this year's draft and had one of the best amateur stride patterns I’ve seen:
From time to time this athlete will struggle with slight misdirection and postural control, but his ability to pitch 92-96mph with above average off-speed offerings is a testament to the balance and power in the lower half of his delivery.
At the end of the day, everyone is going to present with different levels of mobility, stability and coordination, so you certainly have to leave room in your model to account for individual variance. However, these athletes are good examples of how properly maintained mobility and stability can tie into the high-level delivery to make you a more powerful and durable pitcher in the long run.

In today's guest video blog, Cressey Performance Pitching Coordinator Matt Blake talks about stride foot alignment and its effect on the pitching delivery. Matt is an important contributor on the Elite Baseball Mentorships team, and in this post, he breaks down how Kansas City Royals pitcher Tim Collins' stride foot alignment changed over the course of the past few years as he dramatically improved his K:BB ratio in the big leagues.
I love writing features with multiple installments because it really allows me to dig deep into a topic of interest. It's like writing a short book, with each blog being a different chapter. That said, here were a few of my favorite features from 2012 at EricCressey.com:
1. Quick and Easy Ways to Feel and Move Better - This weekly series was largely put forth by Cressey Performance coach Greg Robins, and it includes five tips for taking your nutrition and strength and conditioning programs to the next level. I contribute here and there, but the majority of the praise goes fully to Greg. Here are the five most popular posts from this series in 2012:
Here's a little sample of the kind of content Greg kicks out each week:
2. Coaching Cues to Make Your Strength and Conditioning Programs More Effective - I started this (ongoing) feature in early 2012, and it was a huge hit. Apparently, people love the idea of having some cues they can use in place of having a qualified coach right there with them. Here were the ones we ran this year:
3. Increasing Pitching Velocity: What Stride Length Means and How to Improve It - This three-part series was very popular with my baseball audience, as preparing the body for an appropriate stride is key to pitching success.
In the first half of this two-part installment on why pitching velocity changes during the course of a season, I outlined 9 Reasons Pitching Velocity Increases Over the Course of a Season. As you'll appreciate after reading today's post, there are actually a lot more ways by which pitching velocity can decrease over the course of a season. Let's examine them individually:
1. Body weight reductions
This is far and away the most prominent reason pitchers lose velocity as a season goes on. In fact, it's so big a problem that I devoted an entire blog to it: The #1 Cause of Inconsistent Pitching Velocity.
2. Strength loss
As I discussed in my first book, The Ultimate Off-Season Training Manual, strength is an important foundation for power. And, taking it a step further, power is certainly an important part of pitching. As the season goes on, many guys just don't get in the quality weight room work they need to maintain strength, and power on the mound tails off.
3. Injury
It goes without saying that if you're hurt, you won't throw as hard. This isn't just a shoulder or elbow thing, either; sprained ankles, sore hips, tight lower backs, oblique strains, and stiff necks can all wreak havoc on velocity. If something is bothering you, get it fixed before it causes you to develop bad habits.
4. Loss of mobility
When people hear the word "mobility," they typically just of tissue length. However, mobility is simply one's ability to get into a desired position or posture. In other words, it's a complex interaction of not just actual tissue length, but also strength/stability, tissue quality, and kinesthetic awareness. If you don't continue working on mobility drills, static stretching (when appropriate), foam rolling, and your strength training program, one of the components of this equation can suffer.
Obviously, as I wrote previously What Stride Length Means and How to Improve It: Part 1, Part 2, and Part 3, stride length is the best example of this phenomenon. However, what happens at the shoulder is another great example, too. One who loses thoracic mobility or scapular stability may stiffen up at the glenohumeral (ball-and-socket) joint; it's possible to gain range of motion without even stretching at the "stiff" joint!
5. Excessive workload
This is the time of year when a lot of guys start hitting all-time highs for innings in a season. And, with the games getting more important at the end of the high school and college seasons, pitch counts often rise when the innings really matter. It's very simple:
Fatigue masks fitness.
If you're dragging and the velocity is down, a short-term reduction in throwing volume is often the quickest path to getting velocity back - particularly in pitchers who are throwing more innings than ever before. Throwing an easy flat-ground instead of a bullpen between starts is one way to stay fresh, or you may opt to alternating higher pitch counts with shorter outings. If I hear about one of our high school pitchers who has an exceptionally high pitch count (105+), I usually tell him to make sure the next one is in the ballpark of 80 pitches. At that age, arms always seem to be dragging if kids go over 100 pitches in back-to-back outings.
6. Cumulative effect of bad throwing programs
This is best illustrated by a "hypothetical" example that actually happens far too often.
a. Pitcher makes great velocity gains in an off-season with comprehensive throwing program that includes long toss.
b. Pitcher goes in-season and encounters pitching coach that doesn't believe in long toss as part of a throwing program.
c. Pitcher has a velocity loss.
This scenario doesn't just happen because a specific modality (long toss) is removed, but also because of the effect it has on a pitching routine. This, for me, is why it's so important to have conversations with pitchers on what throwing programs they've done in the past. What's worked? What hasn't? It's all about tinkering, and rarely about overhauling.
These researchers divided a collegiate pitching staff into two groups of eight pitchers over the course of a season, and each group did everything identically – except the running portion of their strength and conditioning programs. Three days per week, the “sprint” group did 10-30 sprints of 15-60m with 10-60s rest between bouts. The endurance group performed moderate-to-high intensity jogging or cycling 3-4 days per week for anywhere from 20-60 minutes.
Over the course of the season, the endurance group’s peak power output dropped by an average of 39.5 watts while the sprinting group increased by an average of 210.6 watts. You still want to distance run?
Of course, there are still the tired old arguments of "it flushes out my arm" (much better ways to do that), it clears my head (go see a psychologist), "it keeps my weight down" (eat less crap, and do more lifting and sprinting), and "it helps me bounce back better between starts" (then why are so many players in MLB living on anti-inflammatories?). The system is broke, but instead of fixing it based on logic, many coaches continue to change the oil on a car with no wheels.
8. Insufficient warm-ups
While there are definitely some outstanding opportunities out there to develop in the summer, the truth is that summer baseball is notorious for sloppy organization. Guys are allowed to show up ten minutes before game time, do a few arm circles, and then go right to it. If you're walking directly from your car to the mound, don't expect your velocity to be too good in the first few innings.
9. Cumulative effect of altered sleep patterns
Early in my training career, I realized that missing sleep the night before a training session really didn't have any effect on my next training session. However, if I had consecutive nights of little to no sleep, it crushed me. I know of a lot of people who are the same way.
Now, imagine an entire season of red-eye flights, 3AM bus departures, and going to bed at 1am every night. Beyond just the sleep deprivation component, you have the dramatic change in circadian rhythms that takes place. Just head over to Pubmed and look at the hundreds of studies examining the health impact of working night shifts (shift work disorder); you'll see preliminary research linking it to increased risk of cardiovascular disease, cancer, and a host of other issues. I firmly believe it's one of many reasons injuries in baseball are on the rise - and certainly one potential culprit when velocity declines as a season progress.
10. Pitching off a crappy mound
Many players wind up pitching off terrible mounds during summer ball, and when the mound isn't groomed nicely, you get into "oh crap, I don't want to get hurt" mode with your landing leg. If you aren't comfortable landing, you shorten your stride, or reach for a "safe" part of the mound, messing with your mechanics in the process. Additionally, velocity is going to be lower when the mound height isn't as elevated; it's just how gravity works.
11. Mechanical tinkering for the bad
In part 1, I noted that mechanics changes in the summertime can be a source of velocity improvements. They can also, however, be a reason for guys losing velocity. Not all changes are new changes, and it's important to be careful about overhauling things on the advice of each new coach you encounter. Repetition is important, and it's hard to get it if you're always tinkering with something.
12. Dehydration
Dehydration can have a dramatically negative effect on strength and power. Most athletes are chronically dehydrated at rest, and certainly during pitching outings in the summer heat. Hydration status is an important thing to monitor if you want to throw gas.
13. Throwing to a new catcher
Being comfortable with the guy who is catching your pitches is a big part of success on the mound. When the catcher is constantly changing, there is more hesitation - especially if his pitch-calling tendencies are different from those of your previous catcher. If you're constantly shaking him off, it'll mess with your pace on the mound and slow you down.
14. More erratic throwing schedule
One of the biggest adjustments a pitcher will ever have to make is switching from starting to relieving or vice versa. While going to the bullpen can often lead to an increase in velocity, it can make other guys erratic with their delivery, as they've learned to rely on the pre-game period to get everything "synced up."
Meanwhile, thanks to an increased pitch count, guys who go from the bullpen to the starting rotation sometimes see a drop in velocity. As examples, just compare John Smoltz or Daniel Bard out of the bullpen to what they have done in the starting rotation.
The only thing tougher than making that switch is to constantly bounce back and forth between the two, as it really hurts your between-outings preparation. How you prepare to throw seven innings is considerably different than what you do if you're just going to go out and throw 10-15 pitches.
These are only 14 reasons velocity may dip, and their are surely many more. Maybe your girlfriend cheated on you with the bat boy and you got distracted, or you decided to just throw knuckleballs. The point is that - as if the case with many things in life - it's a lot easier to screw up (lose velocity) than it is to thrive (gain velocity). Plan accordingly!

With spring training upon us, I thought I'd draw this week's exercise of the week from a recent video shoot I did with Stack.com and New Balance Baseball at Cressey Performance with two of our big leaguers, Tim Collins (Royals) and Steve Cishek (Marlins) . In this video, Tim demonstrates the Figure 8 Rotational Medicine Ball Shotput while I do the voice-over.
Most of my comments serve as a general overview with respect to how we approach medicine ball workouts in general, but there are a few key points/observations I should make with respect to the Figure 8 drill in particular.
1. Notice (especially at the 1:20 mark) how Tim works to keep his head back prior to aggressively rotating through the hips and "launching" the ball. This piggybacks on something I discussed in my recent posts on increasing pitching velocity by improving stride length; if the head comes forward, you'll leak energy early, as opposed to storing it and snapping through with aggressive hip rotation later on. Notice Tim on the mound; his head (and, in turn, the majority of his body weight) remains back well into his delivery.
This drill helps to teach guys how to control and time their weight shift.
2. A while back, Matt Blake wrote up a good piece on how we utilize the Figure 8 drill with pitchers; you can check it out HERE.
3. Some folks will make the mistake of going too heavy on this drill. The med ball shouldn't weigh any more than ten pounds - and we usually stay in the eight-pound range. Making the med ball too heavy won't just interfere with generating the ideal power; it will also lead to athletes creating too much tension in the upper traps and levator scapulae to resist the downward pull of gravity. This gives us too much tension in the neck and upper back, and interferes with the good "scap load" and long deceleration arc we're trying to create.
I hope you like it!

In part 1 of this series, I touched on some of the mechanical factors one must consider in relation to increasing stride length in pitchers. Then, in part 2, I got discussed physical factors – hip mobility and lower-body strength/power – that govern how far you can stride. In wrapping up today with part 3, we’ll work our way up the kinetic chain to discuss three more physical factors that control stride length.
3. Rotary Stability – As I discussed in my recent article at T-Nation, What I Learned in 2011, hip mobility “sticks” better when you have adequate rotary stability, so we’ve been doing more of our core stability exercises in more “extreme” positions of hip mobility.
If you’re going to push the limits of hip abduction, internal, and external rotation range of motion, you need to be sure that you have adequate rotary stability to be stable in these positions in weight-bearing and not destroy the spine. Anybody can just get into these positions in slow speed, but not everyone can control the body precisely with a combination of isometric and eccentric muscle action at the high velocities we see with pitching.
Additionally, many of the big-time long stride guys rely heavily on controlling lumbar spine hyperextension as they ride the back hip down the mound. This is something you’ll see if you watch the deliveries of smaller, athletic guys like Tim Lincecum, Tim Collins, and Trevor Bauer. If they don’t maintain adequate anterior core function, they’ll wind up with extension-based back pain in no time.
4. Thoracic Mobility – Throwing and hitting (and really any rotational challenge like a hockey slapshot or tennis stroke) present a unique challenge to an athlete: the hips and shoulders are temporarily moving in opposite directions. This creates separation, which allows an athlete to store elastic energy and create velocity via the stretch-shortening cycle.
The first issue to consider is that not all separation is created equal. You can create separation with the hips and lower back – and jack up a lumbar spine over time. The goal is to having adequate thoracic spine mobility to ensure that this separation occurs higher up (and engages the upper extremity well).
The second issue is that the more you push the limits of hip mobility, the more you must push the limits of thoracic mobility. We’ve always heard “equal and opposite” when it comes to the throwing arm and glove arm, but the truth is that it probably apply to the lower half and thoracic spine as well. You simply don’t see guys with terrible thoracic mobility getting way down the mound, as that lack of thoracic mobility would cause them to leak forward with the upper body. I covered this in part 1, but the Cliff’s Notes version is that the head doesn’t stay behind the hips long enough, so throwers lose separation.
The third issue is that poor thoracic mobility will really interfere with getting an adequate scap load, so the arm speed will be slower. Throwing with a poorly positioned scapula is like trying to jump out of sand; you just don’t have a firm platform from which to create force.
A very basic thoracic spine mobility drill that would be a “safe” bet for most throwers would be the quadruped extension-rotation.
This drill doesn’t crank the shoulder into excessive external rotation, which may be a problem for the really “loose” arms in the crowd. Progressions for the really stiff pitchers would be the side-lying windmill and side-lying extension-rotation. I also like the yoga plex, a drill I learned from Nick Tumminello, as a means of syncing everything up with a longer stride.
Note: be sure to read this shoulder mobility blog on why not all thoracic spine mobility drills are created equal for throwers!
5. Quick Arm – When I say that you have to have a quick arm to have a long stride, I really just mean that you need some upper body power to make things work. The longer the stride, the quicker your arm must be to catch up in time to create a downward plane and throw strikes.
You simply don’t see guys with long strides competing at high levels unless they have a quick arm that can catch up to the lower body.
When a guy’s arm isn’t quick enough to catch up to his lower half, you see him miss up and arm side.
This type of thrower would be better off shortening up his stride (at least temporarily) and spending more time on good throwing programs to increase arm speed.
This is one reason Justin Verlander is great. If you watch him, he’s not an insanely long stride. Rather, he’s shorter with it, and much stiffer on his landing leg to create an awesome downward plane. Plus, he actually does have a ridiculously quick arm and outstanding secondary stuff. A lot of pitching coaches would try to lengthen his stride – and while this might work, I don’t know about you, but I think overhauling a Cy Young winner’s mechanics is silly.
The “long stride, slow arm” issue is (in my experience) most common in young, lax players who have the joint range-of-motion and just enough stability to get a long stride, but don’t have adequate arm speed to catch up. This is really common in the 14-17 age ranges, and I think it’s one reason why so many of these kids respond incredibly favorably to long toss; it teaches their arms to go faster and keep up with their strides.
Conversely, as you start to deal with 18-year-olds and older (or kids who have grown quickly), you start to see that preparing everything below the arm is arguably more important than arm speed. You don’t pitch in college or professional baseball unless you have a reasonably quick arm, and getting more aggressive with the lower half to stride longer is often exactly what guys need to make the big velocity jump. Likewise, when guys don’t take care of the lower half, but continue on aggressive throwing programs, they often wind up with velocity drops, injuries, or control issues because they’ve lost the separation that made them successful.
Closing Thoughts
While a long stride can certainly be advantageous in the throwing motion, as I've shown in this series, forcing it when you don't have the right physical preparation or mechanical coaching in place can actually hurt an pitcher's performance and health. Remember that the best changes are subtle ones; in other words, you might increase a stride by six inches over the course of a year, not in a single session.

In part 1 of this series, I discussed the fact that – all other factors held constant – increasing stride length will improve pitching velocity. Unfortunately, when you simply tell a pitcher to stride further down the mound, there are usually some unfavorable mechanical consequences that actually hinder pitching velocity. So, be sure to read that piece before continuing on here.
That said, sometimes, physical limitations can make it difficult to acquire a longer stride. To that end, I wanted to use this second installment to begin to outline the top five limiting factors for those looking to get down the mound and throw harder.1. Hip Mobility
If you’re going to really get down the mound, you need outstanding adductor length on both the lead and trailing legs. That goes without saying. While we outline several options on our Assess and Correct DVD set, the split-stance kneeling adductor mobilization is definitely my favorite, as it improves adductor length in both hip flexion and extension:
Just as important, players need to stop “hanging out” in adduction in sitting and standing. I wrote about this in a bit more detail in my What I Learned in 2010 article (point #3). This is incredibly common in right-handed throwers, in particular. If your resting hip posture looks like this, fix it!
We use a variety of drills from the Postural Restoration Institute to help address the issue, but suffice it to say that you’ll be swimming upstream unless you learn to stop standing/sitting like this!
Additionally, you need adequate length of the trailing leg hip flexors – particularly rectus femoris – to ensure that you don’t cut off hip rotation prematurely. I like the wall hip flexor mobilization for this purpose. Keep in mind that we perform the exercises on both the front and trailing leg, as many pitchers will have substantial knee flexion deficit on the front leg secondary to the stress of landing/deceleration.
Third, you need adequate hip internal and external rotation on both sides. Hip external rotation range-of-motion on the trailing leg is particularly important to allow force to be applied over a longer distance. Additionally, hip internal rotation is key on the front side, as enables a thrower to utilize the lower half more efficiently in deceleration. Those without adequate internal rotation on the front side often cut their arm paths short and miss high with pitches – and put much more stress on their arm because the deceleration “arc” is shorter.
External rotation is best gained through glute activation drills (supine bridges, side-lying clams, x-band walks) in conjunction with simply externally rotating the femur during the split-stance kneeling adductor mobilization I featured earlier. For internal rotation, I like a gentle knee-t0-knee stretch/mobs (assuming no medial knee issues) , and bowler squats as a follow-up to get comfortable with the pattern.
Of course, all these mobility drills must be complemented by quality soft tissue work: foam rolling and, ideally, manual therapy with a qualified practitioner.
So, as you can see, adequate hip mobility for optimizing pitching velocity must take place in a number of planes. Additionally, you need to remember that mobility is always influenced by musculo-tendinous. capsular, ligamentous, and osseous (bony) restrictions, so no two pitchers will be the same in their needs. And, some pitchers simply may not have the bone structures to get into certain positions that are easy for other pitchers to achieve.
2. Lower-Body Strength/Power
You can’t discuss lower-body mobility without appreciating the interaction it has with lower-body strength and power.
You see, mobility is simply your ability to get into a certain position or posture. Flexibility is simply the excursion through which a joint can move. What’s the problem?
Flexibility doesn’t take into account stability. Just because you can get your joints to a certain position in a non-weight-bearing scenario doesn’t mean that you’ll be able to achieve that same position when you’re in a weight-bearing position, trying to throw 95mph as you move downhill. So, I’ll put my point in big, bold letters:
Pitchers need strength to have mobility.
Truth be told, building lower body strength in throwers isn’t tough. You use all the basics – single-leg work, deadlift variations, squat variations (when appropriate), sled work, pull-throughs, glute-ham raise, hip thrusts, glute bridges, etc. – but just work to make sure that they are safe for throwers (e.g., use the front squat grip instead of the back squat grip).
Strength isn’t just a foundation for mobility, though; it’s also a foundation for power. You can’t apply force quickly if you don’t have force! So, once players have an adequate foundation of strength, they can benefit more from rotational medicine ball exercises and plyos in the frontal/transverse planes to learn to better apply force outside the sagittal plane.
Make no mistake about it; having adequate strength/power to push off and rotate aggressively – not to mention decelerate the body on the front leg – is essential to outstanding pitching velocity.
I’ll be back soon with Part 3 of this series. In the meantime, if you’re looking for more hip mobility ideas for baseball players, check out Assess and Correct: Breaking Barriers to Unlock Performance.
