I've experienced real back pain before. The kind of pain that shoots through all the muscle fibers in your back if you just move a centimeter. It's the kind of pain that keeps you stuck in a crumpled fetal position and doesn't go away. It's the kind of pain that feels like someone hammered a nail into my spine and there's nothing I can do to pull it out.What Ben seemed to be experiencing was the kind of discomfort you get from the build up of lactic acid when you haven't worked out in a long time or forever. I'll feel that if I work out hard at the gym after a month of slacking off. It's nothing. You push past it and go. In fact, one of the faster ways for me to get over the discomfort of built up lactic acid is to work out even more.With his curtain drapey body, Ben looks like he hasn't worked out or lifted anything heavy anytime in his life.
