If you mean the Barry's Bootcamp (5 Day Academy), which cardio I thought was challenging - Insanity is tougherAlthough Insanity is much more fun. I'm not watching the clock with Insanity whereas Barry's Bootcamp I'm checking the time 5 minutes into the cardio workout.
Thanks for all the input. I guess I am one of the few who liked BBC cardioI thought all the plyo moves really leaned out the lower body.
Sounds like insanity is really insane!
