Floor I-Position Raise

Start: Lie facedown on the floor. Extend your arms above your head and rest them on the floor, keeping them straight and in line with your shoulders, palms facing each other and thumbs pointing toward the ceiling. Your body should form a straight line from your feet to your hands.

Movement: Squeeze your shoulder blades together and down to raise your arms a few inches off the floor, keeping them straight. Pause, then slowly lower back to the starting position. That's one rep.
