I bought this because I wanted something that would be fun, and that involved "dancing", not just a lot of arobic exercises strung together with no flow,etc. I'm 29 and found this set to be really entertaining, fun, and even a good work-out. I was worried about how much of a work-out I would get when I ordered the DVDs, but now that I've done them I see I sure didn't have to worry. About half way through each DVD you really start to feel the burn. Doing these and eating right for 1.5 weeks and I had already lost 3 lbs. Although some people laugh when I say I bought these and love them, that's ok. It's so worth it. And I mean, how can anyone not love Richard's zeal for life? I get some good giggles from him now and then during the routines. One word though, the final DVD in the set is a life lesson kind of thing, not a work-out (you can see this in the description). Although the message is good in it, it's very, very corney and the editing, etc., leaves something to be desired. That's the only down side to this though. Great product and a great price for it!
