The Side Leg Lift Series is an original Pilates exercise that targets the muscles of the inner and outer thighs. Performing this exercise on the Bosu challenges core stability and balance to increase core strength and tone the muscles of the torso. You’ll experience flatter abs and more shapely legs in no time!
