I like this video. I do it every other day, alternating with STTO 2. I started 3 months ago, as a complete beginner (at 49) at this sort of thing but thought I might prefer this type of exercise over walking (and walking and walking) as part of the program reccomended by my doctor to lower my blood pressure and help reduce the cholesterol count. It wasn't difficult to learn the routines , though there are still parts where I get caught out, but mostly I catch up pretty quickly. A couple of things irritate me about both, they each have one song with a routine that I loathe, mostly because I can't do part of it. In STTO 2 its Jailhouse Rock , the first part is almost impossible for me to do on a carpet, in 3 its The Name Game which has a lot of redundant hand and arm gestures and the whole thing is just a bit silly. Having said that, I get round it by doing my own thing , picking up the routine again when its gets more worthwhile. I think I prefer 3 despite this, its fast and fun and it has certainly helped me to lose (with diet) 33lbs.
