Reps: 12 each side
- Start lying on your left side with your weight on your elbow. Your legs are almost straight and your feet stacked with the right on top. Inhale to prepare.
- Exhale, pull your abs to your spine, and lift your pelvis off the floor, coming into a side elbow-plank. Really lift your bottom waist up. Pull your shoulder blade down your back so your shoulder stays away from your ear (this will work your lat, too). You can modify the exercise by placing your bottom knee on the floor.
- Hold for three seconds. Lower your pelvis back to the floor slowly and with control to complete one rep.
Works: shoulder, lats, and obliques
