- Stand with your legs just slightly wider than hip-distance apart, arms raised to shoulder height with elbows bent, holding weights by your ears.
- Bend your knees as if you were sitting in a chair, keeping weight on your heels.
- Press the dumbbells overhead as you straighten your knees to return to standing.
- Complete as many reps as you can in 40 seconds, followed by a 20-second rest.
