Sit on stability ball facing partner who’s holding med ball
As he tosses ball to you, catch it and perform crunch
At top of crunch, throw ball to partner with chest pass
Form matters: “Keep your core tight to absorb the force of the throw and to prevent the stability ball from going all over the place.”
Why he does it: “Because I throw the med ball to all different locations, reaction and stabilization are challenged. Amare has to react to the ball, catch it, stabilize and then perform a controlled crunch.”
