Medicine ball reverse toss exercise is great to develop power. This is one of my favorite ways to develop power. I am a fan of olympic lifts too but medicine ball throws require a lot less skill and and put less stress strain on the body so the risk of injury is somewhat less. When you do medicine ball reverse tosses you either need to have a few medicine balls so you can repeat the throws back to back or you will need to sprint up to the ball and throw again. I use these two methods. A different way to implement this exercise is by doing it against a wall. You can repeat the exercise without the need of additional medicine balls. This is just a different tool to add to your toolbox for building explosive strength.
