This exercise develops coordination and the stabilizers as well as works the leg muscles.
Stand up straight with your feet shoulder width apart. Your supporting leg should be straight, the other should be bent a little at the knee and put slightly forward.
As you inhale, slowly lower yourself bending your supporting leg at the knee, with your other leg extended.
Keep your back straight, you can extend your arms out straight or to the sides.
Try to lower yourself as far as possible.
As you exhale, rise up slowly by extending your leg.
In the beginning you can hold onto some support with one hand.
Do not use weights until you are sure that you can squat deeply enough with your back straight.
Do not bend your non-working leg.
