Looking at a new work out program

So "Crossfit" is actually all over the place. I belive each one is individually owned because it is actually a new way of working out (instead of a gym). I have not personally done it, but my boss does it and he loves it! He noticeable lost a lot of weight as well. I know there are different programs it just depends on what you can afford. If you ahve ever heard of Insanity I have heard from one of the coaches that the workouts are kind of similar. Lots of Interval/cardio/core workouts that are very high in intensity. I also work right next to one and see them a lot doing the different programs. I have heard they are a lot of fun because of the personal interaction you get and I know that it is very similar to having a personal trainer because of the smaller class sizes. Hope this is what you were looking for!
