So I've been spending some time over on the CrossFit boards reading up on it and I like the sounds of it. Is it actually effective? The people on the boards seem to say so but I would like some other opinions. I like the idea of whole body workouts that are varied but I'm not so sure about some things about it. Some of the workouts have you do things like 300 push ups and 200 body weight squats. Things like that just don't seem effective. I would like to start doing some of the workout of the day's and some of the workouts that are named after females (these workouts are always the same and are used to gauge how you have improved I think). What do you guys think?
