- Start on your hands and knees. Relax your shoulders over your wrists, and keep your neck and back long.
- Engage your abs as you extend one leg straight back and the opposite arm straight forward.
- Lift your arm and leg, continuing to actively reach forward and backward with your arm and leg.
- This counts as one rep. Repeat for 10 reps, then switch sides and do another 10 reps.
