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).
- Hold for three seconds. Lower your pelvis back to the floor slowly and with control to complete one rep.
