They say the best way to learn a foreign language is to immerse yourself in that culture. The same can be true of skill development, strength and conditioning, and sports medicine. (1/3)

What started out as a conversation came out quite nicely

Here's a simple but effective strategy to help out your front squat technique. Check it out.

Progressions and Regressions (Thread):

Knowing what movement you are trying to improve and how get each athlete there is paramount when programming for them. You can see this athlete has very little active control of hip IR on his trail leg during the 90/90 switch..

I love hollow rocks. Here’s a way to progress them and make you hate (love) them even more

While digging deep into the @drivelinebases YouTube channel, I found this little gem from 2012.

People often think that you use heavy balls for arm strength (whatever that term means), and light balls for arm speed...might wanna #checktape on that one.

The day I placed the Zepp App on his bat was the moment I realized I taught my son the wrong way. From that moment, I went berserk to find the truth. Through our failures, I will ensure that all of my students regardless of age get on the right pattern for when it matters.

This thread is a long way of saying this: the movement of the glove arm serves as a slingshot mechanism to propel the torso rotation in many high velocity pitchers. This cannot occur in a scenario where equal and opposite patterns are exhibited.

[Matt Daniels @mattdaniels_008]

Eventually, the SHA on the glove-side reaches its end range of motion (which varies athlete to athlete) before the athlete cannot hold counter-rotation any longer. Its this action of the glove-side SHA initiating the torso rotation that’s referred to as “positive disconnection.”

The game of baseball, and life, for that matter, doesn't owe you anything. You aren't entitled to success. Earn it. Chase it. Become it.

@TreadAthletics @plewisbaseball A cue I heard from Ben a while back re: staying into the heel was taking the drive leg back pocket towards the target

[Ben Brewster @TreadAthletics]

Here's an easy way to quantify early hip rotation - counting video frames between the back heel beginning to lift and ball release. Elite throwers fall in the 8-10 frame range.

Someone told me to bet on myself one day. Best advice ever gave me, been doing it everyday since.
