Alone, a UCL tears at 34 Nm of valgus torque. A 60 mph fastball yields roughly 40 Nm…so how does the UCL stay in tact when throwing? Strength from the surrounding structures! In-season, make sure to maintain: -Grip strength -Bicep/Tricep tendon strength -Rear shoulder strength

One of the biggest misconceptions out there is that you have to spend hours a day grinding in the gym to see results. Nope. The best athletes I’ve found who make the most progress put in a lot of high effort, high focus work with full recovery, are done in 45 minutes and go rest.
