A medicine ball is a great tool for switching up your workout and it can used for total body endurance training or power training. 
Several of my clients prefer the medicine ball over any other type of training. Medicine balls come in a variety of weights and sizes, the key is to find the one that works best for you and your goal. Below is a list of total body medicine ball exercises and I recommend doing two sets of twenty to thirty repetitions for endurance training. Remember to use a light weight to refrain from injury. Please use a partner during these exercises!!
