Tapout is MMA/ultimate fighting style so kickboxing, abs, theres I think 12 dvds. Some very intense workouts, my fitness increased very quickly.
It's good you are still walking, I need to make myself go to the classes as well, I got sick and haven't been for awhile, and now I feel like I'm dragging my feet and a little embarrassed.
You should come join the May 2013 Exercise Challenge.
Then you'd be accountable to us on the exercise you do =)
