Insanity is a chunk of change so I need some more info before I buy it (wish there were some more detailed clips). Anyway, I want something hard and I know this will be, but I'm leery that after one workout my knees will be toast. For reference my knees are achy after alot of jumping jacks and moves like Cathe's fast feet shuffles using the step. I love Burpees b/c they are tough and dont kill my knees, and if I do moves like a slow plyo jack my knees dont ache as much as when I do faster more jarring regular jumping jacks. So.....would I have to modify too much to get a good workout?? If so, I really dont want to spend the money. Are there some dvds in the series I could do all the way thru with no modifications? Some where I'd only have to modify here and there?? Or should I forget this series altogether?? My Bday is coming up so I dont my hubby spending the money on this if it really isnt a good option for me.
Thanks!!
