How to do it
- Stand tall with your feet hip-width apart and your elbows bent.
- Run in place, driving one knee up to hip height.

- Pump your arms, bringing the opposite hand forward with each knee.
Alternate sides with each rep.
Form tips
- Stay tall and avoid leaning back as your knees rise.
- Aim for quick, light steps rather than stomping.
