Plank With Alternating Shoulder and Knee Tap
- Start in a plank position with your hands underneath your shoulders.
- Bring your right hand to your left shoulder while keeping the hips still, then bring your right hand back to the ground. Repeat this with the left hand.
- Bring your right knee and left hand together underneath your body. Return to the plank position, then switch so you bring your left knee and right hand together. That counts as one rep.
