look, i talk to guys on a regular basis who are all natural (non-steriod users - one of whom is 60 years old!), and can deadlift and squat 400+ pounds and they're not giants in any way. they have muscle mass, and they look strong, but are nothing like the "mr. universe" guys. seriously and trust me, watching one single documentary that talks about steroid use in no way makes you knowledgeable on the subject.
as for power lifters, dude, olympians are carefully tested, and can't use steriods or they'll be disqualified. if you really want to get into a link contest about this, i can post non-steriod power lifter videos all day long. shall i?
as for you losing 45# how much fat did you lose vs. muscle mass? muscle weighs more than fat, so in 5 months, it's entirely possible that you gained muscle, lost fat, and your weight stayed the same. of coursethe question is, while you were on that training regiment, what was your diet like - what were you eating? did you even track it? did you research the regiment you were put on, to see if it was any good? did you do any research at all, or did you just go through the motions on a bunch of machines? how much effort did you put into your lifts? there are so many variables...
i'm sorry if i'm being harsh, but it really gets on my nerves when people badmouth something that's healthy for +90% of the population, and can be greatly beneficial on several different levels, when they have no idea about the subject. i'm glad that "just running around playing hackey sack and turning the radio on and just moving around" seemed to work for you, but in no way is that something you can try to use to help someone else lose weight, gain strength, and become healthier.
