P90X or Elliptical Machine?

there is no miracle program..just hard work..P90X is organized hard work..we could call it T40YJF5 for crying out loud...i recommended it to someone and they've lost 45lbs in 4 months without being committed to a serious diet, given the choice yes... P90X it will work far more muscle groups than an eliptical. it takes alot of work...you can do P90X half ed and not get any good results...so...that being said...alot of sweating..if you're not sweating eeevery time..you're not losing weight..
