- Start in plank position with your hands under your shoulders and your body in one straight line.
- If your knees aren't on the floor, separate your feet so they're about shoulder width apart to help you stay balanced throughout the exercise.
- Place your hands together, directly under your sternum, with the tips of your index fingers and thumbs touching. Your fingers and thumbs should form a diamond or triangle shape.
- Bend your elbows out to the sides, and lower your chest toward the floor. Then exhale to straighten your arms. This counts as one rep.
