Stand on the BOSU ball with the flat side up and your feet about shoulder-width apart. Engage your core and keep your back straight as you lower your hips into a squat by bending your knees and pushing your hips back. Continue until your thighs are roughly parallel to the ground, then press through your heels to return to standing. The unstable surface challenges balance and recruits additional stabilizing muscles throughout the movement.
Log your squat on bosu ball sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
