Do this exercise with a medium-to-heavy dumbbell, a kettlebell, or medicine ball.
- Start standing with your feet wider than shoulder width, holding one dumbbell in both hands.
- With your back slightly arched, push your hips back, bend your knees, and lower your body until your thighs are parallel to the floor and your elbows touch your knees.
- With your weight focused in your heels, push yourself up to the starting position. This counts as one rep.
