Wall Slides

Wall Slides are a great shoulder mobility check to see where an athlete's range of motion starts breaking down to improper form, yet it is also a fantastic exercise when applied to a rep scheme. Though the movement itself is relatively simple, it can become very difficult to keep proper positioning while performing at higher reps. Fatigue will be felt in the deltoids, traps and essentially anything the sun hits on your body at noon. Pay close attention to where your back is while moving through the motion as it's usually the first culprit to cheat. If keeping your back against the wall proves to be extremely difficult, you can move your feet further away from the wall and bend at the knees more, or you can do the same exercise while laying on the floor.
