A wall climb is exactly what it sounds like. Find a wall and climb over it. The wall should be about 6 feet high. Modify to a lower wall if that’s too difficult and find a higher wall as you become more advanced.
A split snatch is an uncommonly used movement, but allows athletes with mobility issues in their shoulders to get lower than they might be able to with a traditional snatch (full squat).
Here’s a video from our friend Coach Mike Burgener:
Update on the wall climb. Find a wall and face away from it. You are goingn to put your feet on the wall and use your hands to walk back to touch your chest to the wall, then walk forward on your hands to a push up position and touch your chest to the floor. Then push back up, walk your hands backward and your feet up the wall and touch your chest to the wall. Rinse and repeat.
