High squats

How to do it

1. Stand with your feet shoulder-width apart and extend both arms straight up overhead.
2. Keeping your arms up and your chest tall, bend your knees and push your hips back into a half-depth squat - stopping before your thighs reach parallel - then drive back up to standing, arms still reaching for the ceiling.
3. The overhead arms are the real work here: they force your back and core to hold you upright while your legs pump through the reps.
