HOW: Stand in between two sturdy objects like boxes, benches, or chairs. Something that is sturdy and won’t flip as you put your weight down into them. Place a hand on each object and with your arms straight, push down into them lifting your legs up off of the ground bending your knees. Hold this position for as long as prescribed.
FEEL: You should feel your core muscles working and your shoulder muscles working while holding your body up.
COMPENSATION: Keep your elbows locked out and at your side, don’t have them in front or behind your body.
