DEADLIFT TO SINGLE-LEG ROMANIAN DEADLIFT

Squat to grab a barbell with an overhand grip (a). Thrust your hips forward as you rise to stand (b). With your right knee slightly bent, lift your left leg behind you, hinging at your hips and lowering your torso until it's parallel to the floor (c). Reverse the movement to return to start. That's one rep; do three or four, then switch sides and repeat.
