Maintain your front knee in line with your toes and do not allow the heel of your front leg to rise off the floor.
Keep your body upright throughout the movement with your head up and your gaze forward.
Stand by pushing through your front leg hip and return to the starting position.
Take time to regain your balance after each repetition.
