I have been power lifting in gyms since I was a teen, back in the fifties. That, like modeling, has been a lifetime obsession. I have always had that drive that would push me to finish those large dioramas and relentlessly keep pushing myself at the gym. In the seventies and eighties I got into power meets and competition. As part of that regimen, I also ran, (not jogged), daily, usually 2-5 miles. My wife Susan was always there with me, way back when women didn't do those things. She is a little woman, not that much taller than Jenny, but for years could squat 260 pounds at a body weight of 110. She never had the body type to become muscular, just looked very fit. To see her move that kind of weight was quite the sight to behold!
I believe that, as we are still going strong, (and I am going on seventy years old), I can still compete with, (And usually beat), any twenty to forty something in our gym. My all time highs, at a body weight of 185, was 378 bench, 655 squat and a 700 pound dead lift. Those were respectful numbers. I can't quite match those today, but I can still come fairly close. We both still enjoy it and work out regularly and religiously four days a week. We walk/run 7 days a week.
This picture was taken in 1991, I was about 50. Yes, I was wearing shorts!

Susan calls this my Adam in Eden pic. She laughs every time she sees it!
This was taken in 2008. I was 67, and Luca Marchetti of Pegaso Models had sent me a case of Chianti Classico. I sent this to him and said, "Look what drinking vino will do for you"!
I would recommend this hobby to anyone as strongly as I would modeling.
