Stand with your feet spaced at shoulder width.

With a straight back, hinge forward from the hips, lowering your torso as far as possible before your back begins to round or you feel a strong stretch in the hamstrings, then slowly hinge back to the start position. Maintain a slight knee bend and tense your core to keep a straight back throughout. Repeat for the desired amount of repetitions.

Avoid bending the back or hinging too far down.
