STARTING POSITION:
Stand straight with your feet shoulder width apart in front of a chair. Grab the chair with both hands.
MOVEMENT:
Separate your right foot from the other as much as you can. Exhale during the movement. Make sure you only move the leg and your foot is always pointing forward. Return to the starting position in a smooth movement while you inhale. Repeat the movement for the specified amount of repetitions and then switch sides and repeat with the other leg.
TIPS: The exercise key is quality over quantity. The trick is to perform the exercise using proper form.
