If you like slow motion footage of pitchers who throw hard then you're going to enjoy this YouTube playlist.

If your self image of what you could be is much bigger than what you are right now, and that keeps you from doing the things needed to get better because you don’t want people (or yourself) to think you are less than that self image you have. You will never be what you could be.

It wasn’t about doing mechanical work to change the positions I move through, it was about improving my body’s ability to handle load through the ranges of motion that need to be loaded.

Most sense it’s ever made. Improving my body’s ability to lay back (t spine extension, ribcage mobility, scapular posterior tilt) and handle the energy going into layback allowed me to move through the positions needed to for me to throw 85.

Dove DEEP into the motion capture data to find the differences. Everything basically the exact same: positions, timing, angular velos, torques, literally all of it.

Two throws from two different days. Both were 85 mph. One was painful (shoulder impingement), the other was very comfortable as I warmed up to higher velos

Now I purposely undershoot and do slightly more each week. Almost never overshoot with any trainees anymore, and the results are WAY better. I’ve found doing slightly less than you could do each week adds up to MUCH more than overshooting then deloading.

Eventually I’d realize I would have to deload to give my body time to catch up. Weeks of training that could have been done so much more efficiently, plus the time spent away during the deload.

When I hit it right on the nose I was good to go, but when I overshot I would have to take time away to deload. I usually wouldn’t accept that because it was so early on in a training cycle, so I’d force myself to keep going. Telling myself, my body will adapt and figure it out.

Huge mistake I used to make:. Trying to do as much as I could possibly recover from. I’d try and hit that right on the nose, and about 1/2 of the time I’d get it. The other 1/2 I’d overshoot. I literally never undershot.

I strongly believe you will not be as good as you can be if you don’t eventually become self-sufficient.

Plenty of times I’ll purposely make myself unavailable when athletes think they need me, because in that specific situation I don’t think they do and I think they’re using me as a crutch. Me being available in that moment gets in the way of their development.

My job isn’t to keep the athletes that train with me from struggling, it’s to make sure they struggle in the right amounts on the right things.

IMO the older you get, the harder it is to commit the amount of yourself you need to. Job, significant other, kids, rent, other people’s expectations of you, obligations from every direction. If you struggle committing when younger, you will absolutely quit when it gets HARD.

Consistent high performance is so difficult because you need to bring a lot of attention to detail to basically everything, forever. If you’re not actually about that life you can’t constantly fake it, it will beat you down and you’ll stop.

Consistently see guys try and escape problems that come up for them. Get away from it, think about easier / no stress things, alcohol, video games, TV, phone, etc. When you come back to reality, your problems will still be there. You’re just going to have less time to solve them.

I really think there’s one way to throw as hard as possible. IMO there’s different ways to throw hard because there’s lots of pieces involved and with a high enough ceiling you can ride one piece. But currently I think there’s one way to use all of them as efficiently as possible.

As a reliever, learning how to do your pregame throwing + bullpen warm ups in a way that preps you for the game if you get in, but also doesn’t take away from your ability to throw tomorrow at full capacity if you get told to sit down is insanely important.

You will spend more money, time, and effort jumping from quick fix to quick fix than you will staring the actual big scary problem in the face and tackling it. And in the end, you’ll be in the same spot you are now, but with years less time to do the work that actually needs done.

Applying the right throwing stress at the right time is vital to the success of the rehab. But even if you have that dialed, movement issues can completely block progression until they’re improved.
