Stand tall with a neutral spine and your feet slightly wider than shoulder width apart. Hold a barbell in your hands with an overhand grip and hands the same width as your feet. With a slight bend in your knee, hinge your hips back slightly and tip your torso forwards a few inches, keeping a neutral spine throughout. Keep your arms extended with the barbell resting on your thighs. This is your start position. In one explosive movement, thrust your hips forward into the barbell. At the same time pull the barbell up along your body and at the top, rotate your wrists quickly, pushing your elbows up, so you finish with the barbell resting across your collarbones and your palms facing up. Exhale as you do this. Reverse the movement to return with control to the start position, inhaling as you do so. Repeat for the required number of reps (or time).
