I move tin foil psi wheels easier than paper psi wheels. But it might not be so for other people. An exercise for heavyweight I recommend, although I'm not in heavyweight yet, is try to move a cup with your mind. Start with a plastic one, then fill it up halfway. Then get a glass one, fill that up, then use cans. It requires much more energy and concentration than I can even harness at the moment. Hopefully this helps mate. If you want, here's my Skype: Bomber[LAGG].
