How to do a single-arm overhead squat:
- Stand with your feet slightly wider than hip-width apart.
- Hold a kettlebell or dumbbell in your right hand, and straighten your arm overhead. If this is too difficult or you don't have the shoulder mobility, bend the elbow, and rest the weight on your shoulder.
- With the weight overhead and the elbow locked out, keep the core engaged as you bend the knees into a squat, lowering the hips just below the knees (or as low as is comfortable). Extend the left arm forward for balance. (The photo on the right is demonstrating the exercise on the other side).
- Try to keep equal weight in both feet as you stand up, keeping the right arm straight. That's one rep.
