Feeling the burn

It took me many many days, but I finally finished downloading all of this P90x business just to see what the big deal is about. I skimmed some of the videos and my initial impression is "there is no way I can do these workouts," hahahaha 

Like, they're doing 300 crunches a day. Many of which are really two in ones. I can't do that. I think it'd be feasible if perhaps I took it down to 200 a day, and even that would cause me severe pain. Is that allowed? I guess I wouldn't be doing p90x anymore. I think I'm more of a... P90lite type of guy.
