Yeah this is great. 1 Hold your arm out horizontally, make a fist, and tighten all the muscles in your arm. Now have someone put one hand on top of your elbow, and the other hand under your wrist. 2 Have your friend try to bend your arm. If he's about as strong as you or stronger, he should succeed. 3 Now, hold your arm out (again, with just a slight bend at the elbow), and relax all the muscles in your arm. Let your wrist dangle comfortably. Use just enough muscle to keep your arm in the air. 4 Look ahead in the direction your arm is pointing. Feel as though your arm extends out from you hundreds of feet. Imagine reaching and touching a tree or building that is a long distance away. 5 Maintain this feeling, and have your friend try to bend your arm again.
