oh yeah it's def. legit...i started it trying to gain some weight and i was weighing 174 when i started hoping to get ripped and get up to 180....well i started it and in the first month i had lost 7 lbs but i could def. see a difference in my "leanness"!!...lol also yeah wat atlantis said...legs are very very VERY crucial to building muscle...it's very hard to get bigger if you do not work out your legs!!! alot of trainers that i know always tell me that the squat is the best workout anyone can ever do because it works so many different muscles all at once!!!

hope this helps anyone looking for some results!!
