One of my favorite pieces of equipment in my building's fitness center is the Nautilus Gravitron. It uses a bit of anti-gravity magic to reduce your to make it easier to do pull ups or chin ups. I've never been able to do a full pull up before, but thanks to a 230 lb reduction in weight (the maximum the machine allows), I am able to easily lift myself. I can pretend, if only for a while, that I am getting ripped like Dr. Brain, training to become one of his henchmen. The only problem I have is that I must now, unfortunately, reduce the counterweight by 10 lbs to remain at the level I started.
