Lie on the floor face down and place your elbows slightly wider than shoulder width apart while holding your torso up at arms length. Support your weight on your toes and forearms. Keep the shoulders far from the ears retracting your shoulder blades. Contract your pelvic floor and core while keep your body straight.
In a jump, spread your legs and hands wider than your shoulders and bend your arms until your chest almost touches the floor. Return to the starting position in another jump while you inhale.TIPS: Make sure your shoulder blades are always retracted. The exercise key is quality over quantity. The trick is to perform the exercise using proper form. Don't let the hips go down, specially when you move your feet in a jump.
