Reps: 5, each side
- Begin on all fours with your hands directly under your shoulders and your knees directly under your hips. Pull your abs to your spine as you bring your left knee and right elbow together under your torso.
- Keeping your torso stable and level, straighten your right arm and left leg. Reach through your left heel to engage the muscles on the back of the leg and your butt.
- This completes one rep.
This exercise works the core and teaches the abs and back to work together to stabilize the torso. This move will help get your ready for planks, too.
