3 SWISS BALL SQUEEZE WITH LEG ROTATION
Lie on the floor with a Swiss ball between your legs. Hold your legs up in the air and rotate your torso as far as you can left, then back to the start, then to the right. Take 15 seconds to do each side; repeat three times. “This exercise simulates cornering, builds core strength and works your adductor muscles,” says Young.
