I often joke that some of the biggest training successes of my career came about when I was trying to develop one athletic quality, but actually wound up accidentally developing something else that yielded a great return on investment. Medicine ball training might be the absolute best example of this.

Back around 2007, I started implementing high-volume medicine ball training: both rotational and overhead work at least three times per week with our baseball athletes. There was some decent research on how it could positively impact throwing velocity and bad speed, but I found the training protocols in those studies to be really underwhelming. It was just a lot of “three sets of 10 reps” monotony and relatively basic and unathletic drills. by getting more creative with exercise selection, I felt that it would yield bigger returns on power development while keeping athletes more engaged. And, it accomplished both goals.

What I didn’t realize at the time was that it was also simultaneously creating much better movers. You see, all that medicine ball training was chipping away at some important adaptations we needed in the fascial system to prepare athletes for elasticity in more extreme positions of rotation. By manipulating load, the extent to which we pre-loaded, and where we sat on the force-velocity curve, each rep was helping athletes to develop adjustability, something that’s crucial to withstanding the unpredictable nature of many sports.

And, the truth is that what we learned from training with medicine balls, gave rise to open mindedness in similar avenues. The Versapulley allows us to train higher load, lower velocity rotation with more eccentric overload.

Loving rotational rows w/the @VersaPulley. Here, the lower half works as hard as the upper body. Excited to incorporate this more w/baseball guys to train accepting force on the front side. Whatever you put into it concentrically, you have to take on eccentrically – & then some. pic.twitter.com/IsZDLv2uVu

Proteus allows us to train both high and low load rotation with a concentric focus.

Rotational work on traditional functional trainers seems to be a happy medium between the two. I’ll have their place, but you just need to know what to train.

If you’re interested in digging in deeper on the topic of rotation, I would strongly encourage you to check out my new Medicine Ball Master Class. I created this new resource in collaboration with Athletes Acceleration and it includes over 50 exercise demonstration videos, as well as my rationale for including them.
