How bad are they? I've herd some people talk bad about them and some swear by them. I got a weight belt and have been using it about a month, but now I'm not sure if I'm going to continue to use it. I read it's bad for you abdominal muscles and raises blood pressure. The weight belt does seem to help me a lot on deadlifts and military presses though. On military presses I always have a tendency to stick my chest out. I can't do behind the head military presses because I have scoliosis (11 degrees) and it hurts my back.
