Stand with one foot firmly planted into the ground. Establish your balance by ensuring the foot is directly below the navel and the hips are parallel with the ground.      

Extend the arms in front of you and slowly descend, ensuring that the knee remains aligned with outside eyelets of your shoes. The descent is at an exaggerated slow rate, taking 2-3 seconds to hit your button.  

Aim to get a 90-degree angle at the knee and ascend to return to the starting position.
