Stand with your feet hip-width apart and place one foot to the front with your knee slightly bent. Place your rear foot on top of a bench behind you.
Engage your core stabiliser muscles while keeping your body upright and your head facing forwards.
Gently lower your rear knee almost to the floor while breathing freely.
Straighten your front leg to the starting position but do not step or hop back with your front foot. Repeat for the required number of reps before switching to your other leg.
