Grip a barbell firmly in both hands with a supinated grip and hands about shoulder width apart. Stand with your feet slightly wider than shoulder width. With a slight bend in your knee, slowly hinge your hips back and tip your torso forwards, keeping a neutral spine throughout. Keep your arms extended and the barbell close to your thighs. This is your start position. Keeping your torso stationary and your elbows close to your body, pull the barbell up and back towards your hips. Squeeze your back muscles as you do and exhale. Be sure to keep your shoulders and traps relaxed. Hold for a count of one before returning to the start position. Inhale as you do so. Repeat for the required number or reps (or time).
