Stand or sit with your feet stable and hold onto the assisted machine handles. With a light bend in your knees and your core engaged, lean your upper body to one side in a slow, controlled motion, feeling the contraction along the side of your waist. Return to upright and repeat on the other side. This movement targets the muscles along your waist to improve strength and flexibility without jerking or twisting.
Log your assisted side bent sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
