- Stand with your feet shoulder-width apart and slightly turned out, in a deep squat. Put your arms in a "goal post" position with elbows bent and close to your thighs.
- Jump up explosively, bringing your feet together and clapping your hands above your head. Keep your core engaged.
- This completes one rep.
- Do as many squat jacks as you can in 25 seconds followed by a 10-second rest.
