- Stand with your feet hip-distance apart, holding a dumbbell at each shoulder.
- Slowly bend your knees as if you were going to sit in a chair, keeping all the weight in your heels. Don't let your knees move beyond your toes, and don't let the knees roll out or in. Squat down as low as you can, keeping your head and chest lifted, your spine long, and your shoulders relaxed.
- Press through your heels, and slowly straighten your legs to stand up to complete the rep.
- Complete as many squats as you can with proper form for 40 seconds, followed by a 20-second rest.
