My husband was into bodybuilding when we met 20 years ago (July 7, 1991 to be exact) and he was in great shape - he's 5' 10" and he was cut, probably about 185 pounds -- this photo was taken in 1995, when he was still in great shape just prior to getting out of shape - age 25:
Then he started drinking -- a lot, a 12 pack a night most nights of the week -- and after 8 years he looked more like this at 240 pounds (2003, age 33) --
In August 2008 I quit drinking and in October 2008 my husband quit, too.
In January 2009 he went back into his extreme bodybuilding routine, eating an extremely rigid diet, ridiculous amounts of protein shakes and other supplements, taking a billion vitamins a day, and working out five days a week (20-30 minutes cardio on the bike first, followed by whichever body part(s) are up that day for about an hour/90 minutes, both free weights and smith machine plus other equipment he has down in the weight room/basement).
For more than a year now he's been back down around 200 pounds, pure muscle. He has no body fat, I shit you not:
I took those an hour ago when he got done working out (this was back day but I didn't get any good back photos. He wasn't into posing.)
Not bad for 41, eh?
