1. Stand with feet shoulder-width apart, holding a pair of dumbbells at your sides. Keep your chest up and shoulders back.
2. Bend the knees slightly and keep the shins vertical, hips back and back straight.
3. Keeping your back and arms completely straight, bend at the hips and lower the dumbbells as low as you can without curling your back.
4. When you reach full stretch of your hamstrings, swing the dumbbells out in front of you to create greater tension and then allow them to swing back in as you reverse the movement while contracting your hamstrings to bring you back to starting position.
