If you are looking to Fitness T25 would understand that. It is an ongoing exercise, which of course is a grueling 25 minutes. And terribly tired For people who do not exercise at all. I would recommend that Granted, if you do not want to overdo it by the trainer. You will be in good shape by the advertiser. But consider the availability of our body. I also do not have a full 25 minutes before the first dance for 10 - 15 minutes you'll be tired already. I was so tired I did not stay there for the entire 25 minutes, but the room is a glass of water. I'm a stay-minute And if we do not have to dance with Tania (the right-hand side of the screen) gently back in position. If you have seen it danced by Shaun T goes.
