Squats target quads and glutes and these are muscle groups we use to power most upper body movements (like punching and lunging). They are also used to power sprints, jumps and leaps. They are key to the way we walk and play an integral part in sitting correctly and holding the correct posture. The Super Squat workout helps you achieve all that then in the shortest possible time. Add EC to challenge you further, if you need to.
Extra Credit: 1 minute rest between sets.
