This exercise works your tris one arm at a time; it's also great for glute work.
- Start sitting with your feet flat on the floor, with your hands behind you and your fingers pointing away from you.
- Push your pelvis up as you shift your weight into your left hand, circling your right hand across your body and ending with an overhead reach. Look down toward your left hand and feel an active stretch in your right side.
- Pull your abs in as you lower your pelvis to sit on the floor. This completes one rep. Repeat on the other side.
