STARTING POSITION:
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. Keep the shoulders far from the ears retracting your shoulder blades. Contract your pelvic floor and core while keep your body straight.
MOVEMENT:
Start lowering yourself by bending your elbows until your chest almost touches the floor while you inhale. Push your trunk up with a jump with your arms, clap and put your hands in the same position. Exhale during the ascent. 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.
