I recommend this for those just looking to lose a few pounds and don't have a lot of workout experience or even those who have been working out all their lives. I love being in the gym and working out but being outdoors and working out can't be beat. The vibe is very positive and supportive. The workouts are tailored so anyone can do them no matter what your fitness level. So its what you put into it is what you get out of it. I have seen people in the class lose 50lbs going to the classes daily. I started off not being able to run a mile and now I can run for days and recently completed the Tough Mudder due to going to boot camp regularly.
