I'm going to be brave, please help! :)
I've been saving $$ and am considering a DVD workout program. I'm just not sure which one to do, because my knees are pretty sensitive. I can't do anything super high impact. For example, when I did the 30 day shred I had to do the lower modifications of the moves. I don't want to waste $ on something I won't be able to do, so I am wondering what you recommend.
I've heard good things about p90x and insanity but I am afraid both will be too high impact for my knees. Also, my knee problems are NOT weight related, I've had bad knees since I was about 12.
Are there any workouts that are hard core WITHOUT high impact?
