Wow. So much hating on crossfit. LOL I am not a crossfit member but do drop in to classes from time to time. If there is a good gym near you, you could always drop in to a class and check it out. There is something to be said for the group atmosphere. There is no need to kill yourself in the workouts. I always use less weight than I could do, run a little slower, row a little slower, pull a little less high and frankly no one cares. Like any workout schema, you have to do just enough work to get an effect, but not so much you can't come back to the table the next day. Our gym has people of all ages and sizes and is very supportive and encouraging.
