🚨 Most pitchers are leaking velocity without realizing it… The problem isn’t your arm. It’s your DRIVE LEG. ⚡️ If your back leg collapses inward during the delivery, your body loses force before it ever reaches the baseball. That means: ❌ Less velo ❌ Poor command ❌ More stress...

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?

In from Ohio last week was Chloe Taynor - just an 8th grader but already has a national reputation as a 2-way talent for Indiana Magic Gold 2030 Rogers/Fritsche Chloe added velocity while dropping relative stress on her elbow. We are thrilled to have her as one of our PVS athletes helping keep her healthy and strong with our App as she enters high school next year!!!! Great stuff Chloe !! Her before and after in the 🎥 below illustrates the important topic of arm lay back. Timing and “Layback" in throwing refers to a key biomechanical position in overhand throwing mechanics. The term describes the moment when the throwing arm reaches “maximum external rotation” just before acceleration and release. This is a major problem in Softball, because the sequencing of the act of throwing is often incorrect Ideally, we want The elbow up/near shoulder height. You will see the The forearm and hand "lay back" behind the body (the ball points somewhat backward or away from the target). At this point the shoulder is in extreme external rotation (the upper arm rotates outward), creating a stretched, loaded position in the shoulder and arm muscles/tendons. Layback acts like stretching a rubber band or "cocking" the arm — it stores elastic energy. When the body rotates forward (hips and torso leading), the arm rapidly internally rotates and whips through, generating much higher velocity and power. Better layback often leads to harder, more efficient throws with less arm strain (when mechanics are sound). This is something we test every girl for at the beginning of our sessions and at the end. Layback Matters in Softball Throwing Because it ▪️Increases throwing velocity. Elite throwers show significant layback to maximize the "whip" effect. ▪️Improves efficiency. When proper body sequencing is present hips → torso → shoulder → the arm produces layback naturally without forcing the arm alone. ▪️Reduces injury risk. Good / well timed layback comes from whole-body drive rather than arm-only effort.

Lower body mechanics to throw 95 mph. There are four things about the lower body that I wish I knew when I was a 16 year old throwing 78 miles an hour and trying to throw 90 miles an hour and beyond. The first is the leg lift and how well you're able to start creating momentum toward the target. One of the biggest mistakes people make is thinking they need to fall forward as soon as they lift their leg to create drift. What worked for me was coming to a balance point first and then starting to shift my weight from there. That's still a form of drift, and you see a lot of Japanese pitchers do this, like Yoshinobu Yamamoto. The second component is the back leg and how it creates linear momentum toward the target. One of the biggest mistakes I made was diving too much into the quad. I'd get onto my toes and sink into my quad, which led to less power and actually made rotating much harder. Another mistake I made was squatting as deep as possible into the back leg, almost like a pistol squat. What actually helped me was simply dropping down as quickly as possible. I let gravity pull me down. If you've created enough drift, even just a slight drift, that drop will create linear momentum down the mound. The third component is getting the pelvis to rotate into foot plant. The biggest thing here is matching your pelvis plane of rotation and making sure the pelvis rotates down into foot plant rather than rotating upward. One of my favorite cues for this is to slam the knee down or get onto your shoelaces. The last component is simple. It's the lead leg block. You're trying to block all of the momentum you've created like your life depends on it. For me, I tried to extend as high as I could. That actually helped my pelvis continue to rotate because as the front leg extends, the pelvis gets more open. Those are the four things I wish I knew about the lower body when I was trying to gain pitching velocity.
