* Stand with the dumbbells in front of your thighs and place feet shoulder width apart.

* Take a deep breath and brace your core.

* While keeping your knees stationary and your legs as straight as possible, bend at the waist and push your glutes out while keeping your back straight. You should feel a stretch in your hamstrings.

* Once you can no longer go any lower, stand back up by straightening the torso.

* Repeat for reps.
