Preparation:

.

Stand tall on left foot with the right foot attached to a low cable.

Balance with fingers only as needed, squeezing your stomach tightly.

Movement:

 

Keep your right knee frozen in place. Begin to kick out your right foot.

As the right leg straightens, do not move above the knee joint.

Pause & lift toes up once you have straightened the leg completely.

Hold 1-3" and squeeze your quads tightly.

Begin to lower by slowly bending your knee and allowing it to hinge downward.

Stop bending leg back when the cable weight feels light. Repeat until the balancing leg or moving leg become fatigued.
