Same drill. Same body. 17 MPH difference. 🔥 The top pitcher throws 95. The bottom throws 78. Watch why 👀 ❌ Bottom: his lift leg flies open early — he rotates too soon and his front side collapses. All that power leaks out. ✅ Top: he stays closed, then...

Send this to the pitcher who’s been stuck at 78 all season. Same arm speed. 17 mph apart. The difference is what the front leg does AFTER the foot lands. The 95 guy braces the front leg and lets the body whip over it — that’s 2X, front leg extension. The 78 guy sinks into it, and the energy leaks out the bottom. What the research actually says: - Every 1° of lead knee extension from foot contact to ball release was worth +0.47 m/s of ball velocity — about 1 mph per degree. (Dowling et al., Orthop J Sports Med, 2024 · n = 100 pitchers · R²=0.22, p<.001) - In 322 professional pitchers, the 90 mph group extended the lead knee 17°. The 81 mph group: 5°. (Dowling et al., Sports Biomechanics, 2022) - The braking force in the front leg is what creates the rotational power that gets transferred into the arm. (Howenstein, Kipp & Sabick, J Biomech, 2020) - Stride-leg ground reaction force predicted up to 61% of ball velocity. Drive-leg force predicted none of it. (McNally et al., J Strength Cond Res, 2015) The cue: keep the front knee behind the heel. Brace it — don’t ride it. Want your own numbers?
