Instructions
Stand with a wide legged stance and toes pointed out slightly. With a dumbbell positioned between your legs, on its side and on the floor, squat down and grasp the end with both hands. Keep your arms straight, shoulders tight, head up and lower back engaged (maintaining a strong natural curve). Pull the dumbbell off the floor until your knees, hips and shoulders are locked out. Return the dumbbell by bringing your hips back and bending your knees whilst keeping your back in a strong (not rounded) position.
Tips
The width of your stance will depend on the mobility you have in your hips.
