How to do a single-leg deadlift:
- Hold a dumbbell in each hand, and lift your left foot slightly off the ground.
- Keep your back flat and hips square as you lean your entire torso forward while simultaneously raising your left leg and lowering the dumbbells toward the ground. Make sure to keep your core tight while you move.
- With your back straight, lower your leg and lift your torso up to stand, returning to your starting position. That's one rep.
- Do the same number of reps on both sides.
