Does anyone have suggestions for a good cardio-only workout DVD? I live in a tiny NYC apartment so I don't have a lot of room to work with. I wanted to get back into running again, but between the snow, slush, and bitter cold, that's not going to be possible for a while. I also have Wii Fit and Just Dance for Wii but I find it hard to keep my heart rate consistently up.
I do pilates 3-4 times a week so I don't really need something that incorporates strength training. Just to get my heart rate up for at least 30 minutes a day. Any suggestions? TIA!
