Ask Mike Mentzer how they improved his life.
^^
It wasn't just that that killed him... I've shared this before a few times here, when I was on a two-week vacation while in the Army I chose to come to Los Angeles in 1991 (around there, it was before the Bosnia deployment!!)
and I had read in Ironman magazine he was working out of Gold's doing personal training. I didn't have long to wait, I saw him pull up in a while sports car (I think a Nissan) and I stood up to say hello.
He was a VERY friendly person, we talked for over a half hour (completely lost track of time)- but then enough time had passed that he asked me if I wanted to have a SMOKE with him at the side of the building!!!
I just nervously told him I don't smoke, and he also told me after the day was done he liked to have Jack Daniels too... (no mention of Healthy eating, exotic miracle vitamins, vacations to pristine beaches, etc...)
P.S. This was my "day of come-uppance" or the day the "Veil of Secrecy" was lifted for me, as I TRULY thought the whole game was about Intensity intervals, HEALTH building foods and scientific eating, Gear (administered wisely), and the pursuit of Health-building activities/adventures.
