Both partners: set up in push-up position with feet and hands shoulder width. Face each other, about two to three feet apart. Partner One, roll a medicine ball from your left hand to your partner's right hand. Partner Two, roll it back. Repeat several times on that same side, then switch to your other hand.
Do this exercise with the best exercise equipment. We recommend using a bluetooth chest strap heart rate monitor or a smartwatch for more training optimization & performance tracking.
