Day 4 completed... Working hard on my 60 day challenge prolly will push to the 90 day challenge instead..
interested to see how this goes for you, buzzfeed recently put up a video of four people doing p90x for i think 60 days. ( may be 90). you should YouTube it!
The Buzzfeed challenge was actually really interesting. It also shows that eating right is the path to weight loss though P90x certainly helped with muscle mass.
I've looked at Insanity workouts. . . and they literally do look insane. I'm willing to try it though out of sheer curiosity as to whether I will survive.
