In this intense athletic program developed by the Merrithew Health & Fitness™ programming team, you will experience a unique full-body workout using the medicine ball. Because of the shape and weight of the ball, this program will challenge your strength and agility as well as your endurance and stamina. Based on a series of exercise intervals, incorporating the STOTT PILATES® principles, you can increase or decrease the intensity of the workout based on the weight of the med ball you choose.
