Such an awesome workout! I started Jabz a year ago and am hooked. It is challenging, works all body parts, the trainers are great motivators and everyone is really nice. As I have gotten older(53)it is harder to stay in shape, but with Jabz, my core strength has never been better. It incorporates not just boxing, but all other types of exercise as well to reach every muscle group. If you have never tried it, it is definitely worth it, you'll see results.
