STARTING POSITION:
You need to find a stable wall to do the exercise. Lie on the floor face down and place your hands slightly wider than shoulder width apart while holding your torso up at arms length. Support your weight on your toes and hands. Do a handstand against the wall and fully extend your arms. Contract your pelvic floor and core while keep your body straight.
MOVEMENT:
Start lowering yourself by bending your elbows until your forehead almost touches the floor while you inhale. Press your upper body back to the starting position strengthening you body while you exhale. Make sure your shoulder blades are always retracted.
TIPS: The exercise key is quality over quantity. The trick is to perform the exercise using proper form.
