I’m going to let you in on a little secret:

Your body has its own bank account.

It’s an account full of what we’ll call adaptive currency, and it’s responsible for buying you different fitness qualities. For example, say you want to add 10 pounds to your deadlift…well, that’s going to cost you.

In fact, every decision you make in both life and training impacts the size of your bank account and influences how much “money you have to spend” at any one time.

For those of you out there who have aspirations to perform at a high level, and stay healthy doing so, it’s vital to understand this concept.

Stress and Adaptation

We all have training-related goals:

• look like a Superhero
• cut your body fat down to 6%
• deadlift 500 pounds
• have a 30-inch vertical jump
• bench press 300 pounds
• win a competition in the sport of your choice

Whatever your goal, you're relying on one of the most basic survival/evolutionary mechanisms to make it happen: adaptation.

And let's make one thing perfectly clear: while we may come across as sophisticated humans, deep down, we're still biological animals who survive to pass on as many of our own genes as we can. That's really the name of the game: do whatever you have to do to survive, so you can pass along more genes than the next guy or girl.
It sounds barbaric because it is, but deep down, it's a driving force we can't escape.

Thus, our "system's" number one goal is survival, and it's going to do everything it can to make sure that happens. Enter adaptation: the way in which we react to stressors in our environment to improve our likelihood of survival.
Before we talk about how it works, here are two definitions with which you need to be familiar:

1. Homeostasis: the body’s desire to stay within normal ranges needed to function and survive. For example, your blood prefers to stay within a pH range of 7.35-7.45 because that's where it's happy, that's where it functions well, and that's where we have the best chance of survival.

2. Allostasis: the body’s adaptive response to maintain homeostasis. In other words, how the body manages to maintain homeostasis in the face of a stressor. Think of it like those bumpers you set up in the gutters at the bowling alley: you need to stay within those set limits or else all hell will break loose.

When considering adaptation, this is the basic process* it follows:

*Please know that adaptation, stress, allostasis and everything we're talking about today is an incredibly complex topic. In order to make it more approachable, we're going to dumb it down a bit so you can focus on the big picture. Thus, if you're a big science person, please don't get all worked up because I know there's way more to this than what we're going to talk about today.

Step 1: You provide a stressor.

Step 2: Stressor threatens homeostasis and thus survival.

Step 3: The body, via allostasis, works to maintain homeostasis in the face of this stressor.

Step 4: You adapt to the original stressor in order to limit the amount of stress it can place on your system in the future.

Here's what that would look like in a graph (notice how it resembles a training cycle?):

As you can see, there's a decrease in performance while your body attempts to manage the unfamiliar stressor. Remember, it's trying hard to maintain homeostasis so you can stay alive.

Eventually, however, you adapt (supercompensate) above a level you were at previously. This is to ensure that the same stressor in the future won't have as large of an impact on your system.

Here's an easy example of this process in action: think back to when you first did back squats...what happened?

For starters, they were probably pretty ugly, but I'm also willing to bet you were sore the next day.

What about four weeks down the road when you squatted the same weight as you did on day one; were you as sore and/or beat up the next day?

Absolutely not. Why? Squatting was an incredible stressor the first time you did it. It's something your body had never encountered. But after a few weeks of exposure, your body had started to adapt to the new and repeated stressor to limit its overall effect on the system. This is the reason you must periodize your training; stimuli must change over time to continue the process of adaptation.

To review: your body’s goal is to limit the impact a stressor can have on your system to increase your likelihood of survival, and improve your chances of passing on copies of your own genes.

The way our body makes it all happen is via adaptation and the adaptation reserve.

The Adaptation Reserve

In a far-off land, behind desert and mountainous terrain, guarded by an army of manticores (do yourself a favor and Google that), you'll find your adaptation reserve.

While the adaptation reserve may seem like a mythological creature you've never managed to catch, it's really just your own personal bank account. It represents the resources your body uses to buy new things (adapt).

You have to keep in mind there's a finite amount of resources in this reserve. Think back to a time when you were a kid and saved up money to buy something you really wanted: you passed on buying other goods because you knew you needed to save up "X" amount of dollars to purchase "Y" toy.

Great. However, what happened after you did by the toy for which you’d been saving? You had no more money.

Does that mean you'll never be able to buy a new toy again? No. It just means you have to save up and make deposits into the account until you have enough resources to do so.

But what determines the size of the bank account? How do you make withdrawals and deposits? Is there more than one account?

Your Body's Bank Account

Below is a fictional image of your body's bank account (adaptation reserve), and it's full of your body's adaptive currency.

Feeling good after a restful weekend, you head off to the gym to crush a deadlift session, because you really want to pull 500lbs.

The following morning you wake up and take a look at your imaginary body bank statement to realize you made a big withdrawal the previous day. Hitting deadlifts over 90% of your 1-rep-max must have really used up a lot of your adaptive reserve because the account is vastly diminished.

This, in a nutshell, is what's happening on a daily basis: you introduce or encounter different stressors that act upon your body in a certain way, and then your body uses its adaptive reserve to respond/adapt.

Remember, your main goal is survival, and in order to increase your likelihood of survival you have to limit the impact stressors have on your system.

A More Realistic Story

For as awesome as it would be for your training session to be the only stressor you encounter, that's simply not the case.

Our life is full of stressors: work, relationships, traffic, etc. Each of these has an impact on your system and it's ability to adapt.

It's not as simple as, "Oh, I lifted today, and that's the only stressor I encountered."

Do I wish for both you and me that that's the case? Absolutely. Unfortunately, it's entirely unrealistic.

There's a good chance you’re stressed about a project at work. Perhaps you didn't sleep at all last night because you had too much caffeine late in the afternoon. Or, maybe you think your significant other is cheating on you and you spend all day and night stressing about it.

The point is this: there are an infinite number of stressors in our lives which all detract from our adaptive currency.

The Size of the Bank Account

An obvious question to consider is: how do I increase the size of my bank account?

Besides genetics, which you have no control over, we can relate the size of the bank account to your overall fitness level. Another way of saying the same thing is to improve your GPP or work capacity.

If you've read anything I’ve written in the past, then you should be familiar with the concept of building a pyramid. In order to one day achieve high, optimal levels of performance, you must put in the time and groundwork to build yourself a monster base. That means attacking things like movement quality, base strength levels, aerobic fitness, and a host of other factors.

Depending on where you're at and what your goals are, you'll have to focus on different fitness qualities.
For example, are you a heavily extended stress ball posture with a resting heart rate in the low 70's? If so, you need to spend a fair amount of time doing low-level aerobic work and working on full exhalation because your body could never handle the type of work required to perform at high levels.

As your work capacity improves, however, you give yourself the potential to one day attack a more aggressive training program because you have the adaptive reserve in place to actually be able to handle large levels of stress.

Do you think Zach Hadge (with a 700+ pound deadlift) trained the way he does now eight years ago? Absolutely not. He spent a ton of timing building himself up to handle the volume and intensity levels he trains at now.

Ultimately, if you have aspirations to be a monster in both training and life, you have to put in the work on the front end to build yourself a large bank account.

Withdrawals and Deposits

We began touching on this concept earlier, but when you look at your training program you have to consider what's making withdrawals from your bank account, what's making deposits, and how big of a deposit/withdrawal you're making.

At the end of the day, you're not making progress if you don't have any adaptive currency to spend. To keep this simple, rest and recovery makes deposits to your account. This includes things like active rest days, sleep, and quality nutrition.

Withdrawals, on the other hand, involve all forms of stress.

For example, let's consider three different training loads and the impact they'll have:

1. Stimulative: a very moderate training load from which one can recover quickly.

2. Developmental: this can be broken down further into high, medium and low, but for today just know that a developmental load triggers the adaptive responses and takes 2-3 days to recover from. For reference sake, a developmental load will fall somewhere between a 6-9 on an RPE scale out of 10.

3. Maximal: this is all you have. A true, "I have to do this or I die" type effort. It crushes your system (especially central nervous system) and takes a long time to recover from.

Here's another thing to consider: different types of fatigue. For example, there's a big difference in CNS fatigue (running a sprint) and local muscular fatigue (doing a bunch of curls). In all honesty, you're probably starting to look at separate bank accounts all adding up to one master account – but let's not go down that path today. Just focus on one bank account, and nail down this concept of stress and adaptation in broad terms (you have to see the forest before you can look at the individual trees).

Hopefully this is all beginning to make sense: training is really just an advanced form of stress management. All forms of stress will have an impact on the body, but the extent of that stress depends on things like volume, intensity, training history, genetics, nutrition, sleep, and a host of other factors.

The End

If you take one thing away from this post, please let it be that you view your training goals as goods you have to buy with money.

It doesn't matter if you want to lose weight, gain weight, have bigger arms, squat more weight, run a better 40 etc. etc. because each of those qualities requires an investment from your body, and your body only has so much to give at any one time.

You have to be methodical in the way you apply stress if you ever hope to see big improvements from your training. Just doing high-intensity work for the sake of doing high-intensity work is a waste of time without figuring out where it falls in the grander scheme of overall development.

Ask more questions, don't be afraid to push the envelope, and structure your training and life in a way that sets you up to succeed.

Today's guest post comes from former Cressey Sports Performance intern, James Cerbie. In this post, James builds on a point I'd made a few weeks ago in an installment of Random Thoughts on Sports Performance. Enjoy! -EC

Everyone wants to throw gas.

If you throw 80mph, you want to throw 85mph. If you throw 85,mph you want to throw 90mph. If you throw 90, you want to throw 95mph…and so on and so forth.

For a pitcher, it’s the ultimate attention grabber. The radar gun doesn’t lie, and lighting one up is the quickest way to turn heads.

Assuming you have any semblance of control, throwing hard helps you get a college scholarship, helps you get drafted, and helps you toward the big leagues.

Sorry, but they aren’t handing out many signing bonuses for an 85mph fastball.

Think of it like the 40-yard dash at the NFL combine—everyone is looking for that 4.3 speed because it’s a game changer.

Due to the high premium baseball places on velocity, and the paychecks that can come along with it, weighted ball programs have gained a tremendous amount of popularity over the past several years. Not only that, they can deliver great results. By playing with the force velocity curve, you can see some pretty impressive jumps in velocity over a relatively short period of time.

Eric has written about weighted ball programs in the past, and I’ll just refer you here if you want to read more on the subject.

Unfortunately, a lot of high school and college athletes are jumping into aggressive weighted ball programs without asking the right questions—they end up chasing short-term gains as opposed to setting themselves up for long-term success.

Building a Pyramid

If I asked you to build a pyramid, how would you do it?

Would you start with the base of the pyramid, also known as your foundation, and gradually work your way up? Slowly adding on a layer at a time until you arrive at the top?

Or, would you skimp on the base and spend the majority of your time building the top of the pyramid?

I’m no expert in building pyramids, but I think we can all agree that the first example wins out: a pyramid without a base may get up in the beginning, but it’ll lose out over the long haul.

General vs. Specific Training

The above example illustrates the difference between general and specific training.

The base of pyramid represents general fitness qualities, while the top of the pyramid represents specific fitness qualities (specific in relation to your sport of choice):

For example, a deadlift represents a general fitness quality for a baseball player because we’re developing strength and stability in the sagittal plane while working on the ability to “hip hinge.” None of those qualities are necessarily specific to throwing a baseball, but they lay the foundation for higher-level performance.

A weighted ball program, on the other hand, is about as specific as you can get: you’re performing the exact skill from your sport and doing so with heavier and lighter implements.

This is why so much effort goes into the assessment process before an athlete starts a training program. It gives us a good feel for where they are on the pyramid:

• How’s their baseline movement capacity?
• Are they lacking scapular upward rotation?

• Can they get their hands overhead without driving into extension?
• Are they strong and stable in the sagittal plane?
• Can they get “in” and “out” of both hips sufficiently?
• Do they have appropriate amounts of “core” control?
• Do they have the capacity to control movement in multiple planes of motion?
• Can they stand on one leg?
• Do they have symmetrical total shoulder motion and shoulder flexion?

These represent only a few of the questions we want answers to, but they are all important because it tells us what an athlete is prepared to do at this moment in time, and what they need to work on to progress further up the pyramid.

What can happen in the world of performance training, however, is the inverted pyramid:

This is what it looks like when people rush straight for the weighted ball program. They skip over the all-important base of pyramid and go straight to the top because that’s what’s sexy. Although this structure will produce results in the short run, it doesn’t bode well for long-term success.

General Expresses Specific

If you walk away from this article remembering one thing, please let it be this: your general fitness qualities (the base of your pyramid) puts you in a position to express your sport specific skill.

In other words, they put you in a position to be successful—they give you the ability to get your body in the best position to throw a baseball.

For a baseball player, building up those qualities usually happens off the baseball field. It’s the free play you engaged in and the multiple sports you enjoyed growing up. And, it’s what you do in the weight room. It means doing deadlifts, lunges, push-ups, prone trap raises, and a host of other exercises because it builds your body up towards the ultimate goal: throwing a baseball to best of your ability.

If you skip over that stage and rush straight towards the top of the pyramid, then you’re not only setting yourself up for injury, you’re also leaving gobs of untapped performance on the table.

Tying it All Together

It’s incredibly tempting to jump into the latest and greatest program on the market that’s boasting to add 8mph to your fastball in two months. Before jumping into that program, you have to ask yourself if you’re physically prepared to do so.

Aggressive throwing programs are not bad. In fact, they are one of the more exciting developments in baseball over the past several years. But, it’s vital to remember where they fall with regards to development.

If you’ve put in the time and built yourself a solid foundation, then by all means get on a well-managed weighted ball program. If you haven’t put in the time building yourself a foundation, then start there and work your way up. Your performance and arm will thank you down the road.

Today's guest post comes from current Cressey Performance intern, and former D1 college baseball player, James Cerbie. -EC

What if?

It’s the age-old question that has haunted athletes and competitive people for ages.

What if I had done this? What if I had done that? What if I hadn’t been stupid and done <fill in the blank>?

Unfortunately, these questions will never have answers. It’s impossible to go back and revisit what could have been. Rather, we’re left to look at the now, learn from our “what if” moments, and share our new understanding with another generation. That is where I now find myself.

I’m in the middle of my internship here at Cressey Performance, and to say I’m greeted with the “what if” question on a daily basis would be an understatement. Everyday I get a glance at how we train and prepare athletes, and get to reflect on how I was trained and prepared.

And just to bring you up to speed, I’m speaking to the training and preparation of baseball athletes. I’m currently 24 years old and spent approximately 19 of those years playing baseball. It was my greatest passion growing up and I devoted countless hours to my craft. My hard work eventually paid off as I got to play Division 1 baseball at a great school (go Davidson). But, nevertheless, it’s impossible to wonder what could have been if I had known what I know now.

Here are 6 things I really wish I would have known, or done more of during my baseball career, courtesy of my experience here at Cressey Performance.

1. Get assessed.

I’ve always been a good athlete. That’s not to toot my own horn because I have my parents to thank for that more than anything; it just is what it is.

Because I was always a good athlete, however, I believe certain aspects of my training got overlooked. Number one on that list being an assessment.

Not once, throughout my entire athletic career, did I ever get assessed.

If I got injured or came up short on a certain task it was just chalked up to being an athlete:

“James…these things just happen. You’re a good athlete and getting injured is just a part of what you do.”

Oh really? A stress fracture in my back, multiple hip flexor strains, a pulled quad and a host of other injuries just happen for the sake of happening? Sorry, but that answer always frustrated me. What I really heard was:

“James…you keep getting injured but I really don’t know why.”

Don’t get me wrong, I understand that getting injured is a part of sports. Here’s the difference though: there are fluke injuries that pop up on the rare occasion, and then there’s being “chronically” injured which entails always being nagged by one thing or another.

Throughout my collegiate baseball career, I fell in the “chronically” injured category and would constantly be met with suggestions like:

“Oh, your hamstrings are tight. Just stretch those bad boys a couple times a day and that’ll help.”

“Oh, your hips are tight. Just stretch that and things should start feeling better.”

For those of you who haven’t tried the “stretch it because it’s tight” routine, let me save you the time and effort: it doesn’t work. There’s far more to it than that.

I don’t want to start sounding like a repetitive drumbeat, so let’s get to the point: you need to be assessed. It’s the number one most important thing you can do; it’ll help you stay healthy and take your performance to the next level.

I’ll use myself as example.

The first time I met Eric was about a year after I stopped playing baseball. Having heard great things about him, I visited Cressey Performance for a one-time consultation. Here’s an excerpt from the email Eric sent me, highlighting my “problems.”

“1. Your sit in significant scapular downward rotation, and your humeral head dives forward whenever you extend or externally rotate. These are super common in overhead throwing athletes, and you just took them a step further by also becoming an overhead pressing athlete! You simply don't get enough upward rotation when your arms elevate - and that's a big thing we'll address with these warm-ups.

2. Getting upward rotation and good overhead motion is also heavily dependent on building up anterior core stability. You're extremely lordotic and heavily overuse your lats to not only pull the spine into extension, but also take the scapula into depression/downward rotation. When lats are this overactive, your lower traps don't want to do their job. So, core stability closely relates to shoulder mobility and stability (not to mention breathing patterns and a host of other things). You could also see how your anterior weight bearing negatively affected your squat pattern, and why that counterbalance made so much of a difference.”

He actually talks about some of these issues in this video:

In short, here were my issues:

- I was incredibly extended with an obnoxious amount of anterior pelvic tilt
- I had crazy overactive, short and stiff lats
- Lower trap strength equivalent to that of a 7-year-old girl
- A 6 pack that meant nothing because my core was actually really weak

Cue epiphany.

I finally had answers to my seemingly endless list of injuries throughout college. Almost all of them could be tied back in one way or another to the list above and here’s the frustrating part: nobody had ever looked at these things before or had ever written me an individualized program to address them.

I was merely given generic “athletic” development programs that fed into and compounded my dysfunction.

Moral of the story? Get assessed.

2. Movement comes first.

I always equated problems with strength. I thought strength could solve any deficiencies I had and approached my training likewise. Looking back, I now realize how dumb that was.

More times than not, especially as you get older and advance from level to level, it has far less to do with strength and far more to do with how well you move. Like Gray Cook says, “Don’t layer fitness on top of dysfunction.”

Well, I layered a whole bunch of fitness on top of dysfunction.

This happened because one, I was never assessed, and two, I was incredibly stubborn. The thought of taking a step back to work on movement quality irked me like no other.

“I can squat over 400 lbs. Why am I going to go do goblet squats with an 80 lb dumbbell?”

This was foolish, and something the coaching staff at CP does an excellent job of handling. Because Cressey Performance puts every client through an assessment, they know what a client needs to work on and how to do so properly. Many times, this means taking a small step backward (from the client’s point of view) in order to take an enormous step forward.

Unfortunately, most athletes are like I was. They want to always push the envelope and the thought of taking a step back is almost insulting.

Dear athletes: Please change this attitude.

I can’t harp on the importance of movement before strength enough. Do what you need to do to make sure you move well before you worry about building up strength. Your body and your career will thank you as you stay healthy and reach the highest levels of performance.

3. Focus on the little things.

It’s often the little things that get overlooked the most. These are things like prone trap raises, breathing patterns, soft tissue work and your posture outside the gym. They aren’t sexy and are, to be quite honest, boring.

It’s these boring and non-sexy items, however, that make a big difference.

Putting your full attention into the tiny details of arm care, how you breathe, how you stand, and how you often you foam roll will make the difference between being good and being exceptional.

Luckily, the athletes at CP have a staff that understands this and harps on it daily.

4. Do more single-leg work.

There were few things I hated doing more than lunges, single leg RDLs, split squats, step-ups…really any single-leg exercises. I hated them because I sucked at them.

Tell me to do something on two legs and I crushed it. Put me on one leg (especially my right) and I turned into Bambi on ice.

Okay, so it wasn’t that bad, but it definitely wasn’t my forte.

Instead of forcing myself to conquer this deficiency, I merely found ways to implement as much bilateral work as possible. Seeing as the vast majority of baseball, and pretty much all sports for that matter, are played on one leg, this wasn’t the smartest decision. I would have been far better off doing like we do at CP and hammering single-leg work.

Not just doing lightweight, high rep sets though, but getting truly strong on one leg:

Ultimately, I believe a lot of the success CP baseball players have is because they are forced to get strong on one leg, while most people take my approach and only get strong on two.

Side note: that’s not to say CP athletes don’t get strong on two legs, because they do.

5. Get outside the sagittal plane.

Oh…the beloved sagittal plane.

Visit most weight rooms and you’ll see people living in the sagittal plane:

Squatting…sagittal plane
Deadlifting…sagittal plane
Box jump…sagittal plane

And the list could easily go on. Most sports (and life for that matter), do not comply with this North-South straight-line orientation; they are lived in multiple planes of motion.

Just think through the complexity and mechanics of throwing a baseball. All the things that need to take place to ensure a ball is thrown at the correct velocity, with the right spin and the right trajectory to bring about the desired result. It’s pretty amazing stuff when you consider the minute details.

Here’s another cool little tidbit of info: power development is plane specific. Just because you can generate power in one plane doesn’t mean you’ll do so well in others.

Yup…you guessed it. I missed the boat on this one also.

At CP, however, they get outside the sagittal plane, and do so often. First on this list is medicine ball throws.

They use a lot of different medicine ball throwing routines to help their athletes develop power in the transverse and frontal plane. A great example of such an exercise is the rotational med ball scoop toss:

Second, they implement exercises like the 1-arm kettlebell lateral lunge and heiden:

Lastly, they use off-set loading on exercises; this provides a rotational component to the movement because the body has to resist rotating towards one side vs. the other. A good example of such a movement would be a 1-arm 1-leg kettlebell RDL:

Although this barely scratches the surface when it comes to exercises used by Cressey Performance and the importance of training outside the sagittal plane, I hope it has given you a good frame of reference.

6. More doesn’t equal better.

There’s a time to push it and a time to back off. Being an in-season athlete is not one of the “push” times. Many coaches, however, forget this and continue pushing their athletes as if nothing has changed.

If you read Eric’s blog often (which I hope you do) you’ll know he says, “You can’t add something without taking something else away.” I really wish that quote could be plastered on the walls of weight rooms around the country.

When the volume of swings, throws and sprints picks up because you’ve started the season, then you have to start taking something away.

Having been lucky enough to spend the past few months at CP, I’ve gotten to witness this first hand. As pitchers begin entering their competitive season (when they’re obviously throwing more often), you see a change in the program to reflect the increased volume outside the weight room.

Medicine ball throws are scaled back, if not eliminated completely. Lifts move towards a two-day per week full body structure, and extra movement days are limited.

As an athlete, it’s easy to forget how everything you do adds up. Every swing, every throw, every sprint and every lift leaves traces in your nervous system. And, although you may be awesome, your body can only handle so much. I understand the desire to get in and work hard, but you have to remember that a lot of times, less is more.

Closing Thoughts

At the end of the day, this barely scratches the surface when it comes to things I wish I would have done differently. As opposed to dwelling on that, however, I’d rather write and share my experiences with coaches and athletes so they can avoid making the mistakes I did. Feel free to post questions or discuss your own experiences in the comments section below.
