Need more DVD suggestions pls!

I want something quick (like 20 minutes max) and intense. I have been doing the Leslie Sansone WATP 1 and 2 mile DVD's and they aren't enough for me to feel pushed enough IMO. I do not want to be on the ground- aerobics, whatever, but nothing on the floor! Suggestions please?

She has a 3 miler also which takes about 40 minutes to do and it is tougher than the ones you mentioned. Go on Leslie's web site she has other DVDs. She also has a CD that you can do while walking outside, a Christian based one and others. As far as any others I cannot tell you, I am not too much into working out with DVDs because I am not coordinated for aerobics. But, I like WATP because there isn't a wrong way to do her walks. Chris
