Lying Cross-Body Dumbbell Extension

How to do it

• Lie on a flat bench (or on the floor) and hold a dumbbell in one hand, with your arm straight up over your shoulder and your palm facing away from you.
• Bend your elbow and slowly drop the weight toward your opposite shoulder. When the head of the dumbbell touches your shoulder, reverse the move and return to the start.
• Lightly place your non-working hand on the outside of your working elbow to steady and support it, helping maintain proper form.
