Place your hands behind your head, on your hips or take a dumbbell in one or both hands, depending on how advance you are.

Start to hinge by pushing your hips behind you and letting your chest and stomach lean forwards. If you are lifting your leg, keep it strong and steady with the glute squeezed. Keep your body in a straight line from your head to your hips – don’t arch through your spine or roll through your shoulders.
Lower until you feel resistance in your standing hamstring, then pause at the bottom of the move for a second.
Push through your standing heel to come back to the starting position.
