I have "hotpants" which I think is great. Its a variety of little dance routines which go for about 8 minutes each. You dont feel as if your having a huge workout but you actually do..
I also have areobics oz style fat burner 2. I likes it at first but it gets kinda borning. But honestly it pushes you
And I have a kick boxing one. I havnt done it in ages, its great but extremly tiring and you can feel it the next day
