Peter Lupus was the main body builder in Muscle Beach Party. He’d won several titles in the mid-west and is best known for his role in the original Mission Impossilbe series. Made a few Sword and Sandles flick, too.I started lifting in 1967 at 12 years old. My father and brothers had a collection of assorted weights, mostly what they’d made out of cement and metal in coffee cans and rebar handles. Tree limbs for push ups. Papa was a big believer in calisthenics and swimming. Got a Sears 110# set for Christmas that year. Build a bench out of 2x4s. In Jr high and High School our coachs were the same. Wouldn’t let a runner, baseball, or basketball player near the weights. As a football, wrestling, and weight throwing athlete I had free reign to the Universal Machine (wow). As you say bodybuilding and how the public views it have gone through a lot of changes. When briefly assigned to Colorado Springs in the late 70’s the only place you could buy a copy of Iron Man was at a porn magazine shop.
