1. 1

   Stand facing a wall, about one fist away from it.

2. 2

   Place the palm or fingers of the working arm on the wall.

3. 3

   Walk your fingers up little by little, raising the arm gradually.

   Pause briefly at the highest comfortable point, then slowly walk back down.

Tip: Crawl the fingers up slowly within a comfortable shoulder range; never push through pain to go higher.
