Mountain Climber
From a high plank, drive one knee toward your chest at a time, switching quickly like you are running in place.
How to do it
- Shoulders stacked over your wrists
- Keep hips level with your shoulders
- Drive knees toward the chest, not the elbows
- Stay light on the balls of your feet
Watch out for
- Hips bouncing high in the air
- Shoulders drifting behind the hands
Make it easier
Slow it down and step each foot in instead of switching fast.
