Lie on your front over a stability ball with your legs outstretched, toes touching the floor.
Keep your neck and head in a neutral position while looking at the floor.
Place your hands on the floor.
Tighten your glute, back, and abdominal muscles to achieve a stable position.
Once stable, raise one arm off the ground until the arm is in line with the body.
Hold briefly and then return to starting position.
Repeat with the opposite arm.
