Another 4 star review must bore you all, but they deserve it. Great HIIT bootcamp like workout. I love the heart monitor that tracks your calories. I want to believe that I burned 689 calories when I went I don't care if it's true, but that's what my monitor read. I felt good, great sweat and didn't get injured. I want to give it a 5 but can't because it's not attached to a full gym, the only downside.
