- Mountain climbers: 

1. Start in a traditional plank pose and keep your wrists directly under your shoulders and the weight on your toes.

2. Keep your arms straight and shoulder-width apart.

3. Your back should be arched to keep the core crunched.

4. Draw your belly button in towards your spine to keep your core engaged.

5. Bring your right knee forward towards your chest and then return to your plank position.

6. Now bring your left knee forward towards your chest and bring it back.

7. Continue switching to alternate legs and slowly pick up the pace.

8. Continue running in this position for at least 30 seconds to one minute.
