Upon closer examination it does not add up. I have a feeling somone is pinching that tape in the back of the arm out of the camera's view. I can count only 10 inches from the bottom most to the top most inch shown. So unless this is a real funny shaped arm, i will remain sceptical. Especially since i have seen near 22 inch arms in person and even on a tall individual they look bigger next to the chest and forearm. Look at Arnold's 22 inch arms flexed in the same pose and you will see what i mean. Good looking arm either way, but i would give it 18-20 inces at the most. Nice try though.
