🔥 The Number One Factor in Pitching Success

A 10 yr longitudinal study (Reinold, Wilk 2009) looking at over 1400 MLB pitchers found that on average GH total ROM exceeded 190 +/- 5 degrees; Bigliani et al found that most MLB pitchers have a positive sulcus sign in their shoulder, and 89% also had it in their NON dominant shoulder (so the traits weren’t “acquired”, they were hereditary).
These are just some of the genetic factors that allow success to “just happen” for the talent.
For that reason guys with the REAL talent can do yoga, physical therapy “workouts”, nothing at all, and still throw gas.
Other pitchers have some arm talent-these are the guys that are often tricked by the easy success of high school into complacency, and get stuck and released in Milb.
If you’re the 99% though, you have LESS, and usually MUCH LESS arm talent
That’s why you’ve been stuck at 82-85
You can still get there, but you will need to vastly improve size, strength, and athleticism in order to bridge the gap.
There is no other path
