Sit on edge of bench with feet placed beyond knees. Bend over and rest torso on thighs. Grasp dumbbells with each hand under legs. Position elbows with slight bend with palms facing together behind ankles (as shown) or just to sides of ankles.
Raise upper arms to sides until elbows are shoulder height. Maintain upper arms perpendicular to torso and fixed elbow position (10° to 30° angle) throughout exercise. Maintain elbows height above wrists by raising “pinkie finger” side up. Lower and repeat.
