Reps: Repeat for one minute.
Begin with mountain climbers to warm up. Here's how to do it:
- Start in a traditional push-up starting position — shoulders over hands and weight on just your toes.
- Bring your right foot forward, bending the knee and putting weight on the ball of your foot.
- Swiftly switch legs, bringing the left knee forward while moving the right leg back. It feels a little like running in place in a plank position.
- Do this for one minute.
