How to do Mountain Climbers
- Get into a plank position, making sure to distribute your weight evenly between your hands and your toes.
- Check your form—your hands should be about shoulder-width apart, back flat, abs engaged, and head in alignment.
- Pull your right knee into your chest as far as you can.
- Then switch, pulling that knee out and bringing the other knee in.
- Keeping your hips down, run your knees in and out as far and as fast as you can. Alternate inhaling and exhaling with each leg change.
