I think that if you are able to exercise than you need to. The band is not a miracle cure that is a one stop fix all, you need to put in effort in order to get results. I have lost 92 lbs in a little over 4 months because of very strict portions and a lot of exercise. You get out of it what you put in, please don't rely on the band to do all the work because it won't and you will be sadly disappointed if you think it will. Good luck
