This is a ball, split one arm chest pass with eccentric rebound. So you're going to be in a split stance. You're going to hold the ball on one hand with the other hand for support. So if the ball is on my right, my right leg is back, the ball is on my left, my left leg is back. This is great for any throwing sport, baseball, softball, tennis, but cross, football. Now the reason we're doing the split stance is it's easier to switch feet. The quick switching feet is great for all field and court sports where you have to be reactive. Switch your feet quick. Catching the ball, the rebound portion is great for elastic, the elastic response. So you're storing to release energy and it's great for course ability because it forces you to reflexively breaks. And that's good for posture stability, anti extension, anti rotation.
