Med ball box jump
Tighten that core, hold the ball and perform plyo box jumps! I love holding the medicine ball while performing the plyo box jump because not only does it add weight resistance to the jump, but by holding the ball away from your body you engage your core muscles a little bit more.
Rep ranges generally depend upon the height of the box and weight of the ball. When landing try to land on your "power pads" (forefoot) and when jumping "snap" your knees.
Plyos jumps are great for adding explosiveness, strength and creating quickness in athletes. Add the ball for an even more challenging jump!
