It's #WorkoutWednesday, and today we're showing you how to do the Alternating-arm Ball Cobra. Lay face down on a stability ball with the feet shoulder width apart. Maintain kinetic chain checkpoints. Keep the spine neutral, legs straight, the pit of the elbow pointing straight ahead, and the balls of the feet at the 2nd and 3rd toes on the ground. Draw the abs in and brace the glutes. Lift one arm to the side of the body at a 30 degree angle. If you want to see hundreds of other exercise videos
