- Come into plank position with your arms and legs straight and your shoulders above your wrists.
- With control, raise your right arm up as you simultaneously raise your left leg up off of the ground. Be sure not to rotate at your hip or upper body. Hold for one second.
- With control, lower your right arm and left leg back to the starting position. That counts as one rep. Repeat with the left arm and right leg.
- Complete 12 reps.
- Modification: hold an elbow plank or a plank on your knees for 15 to 30 seconds.
