Jack LaLanne, Founder of Modern Fitness Movement, Dies at 96 (NY Times)

...

A self-described emotional and physical wreck while growing up in the San Francisco area, Mr. LaLanne began turning his life around, as he often told it, after hearing a talk on proper diet when he was 15.

He started working out with weights when they were an oddity, and in 1936 he opened the prototype for the fitness spas to come — a gym, juice bar and health food store — in an old office building in Oakland.

"People thought I was a charlatan and a nut," he remembered. "The doctors were against me — they said that working out with weights would give people heart attacks and they would lose their sex drive." But Mr. LaLanne persevered, and he found a national pulpit in the age of television.

"The Jack LaLanne Show" made its debut in 1951 as a local program in the San Francisco area, then went nationwide on daytime television in 1959. His short-sleeved jumpsuit showing off his impressive biceps, his props often limited to a broomstick, a chair and a rubber cord, Mr. LaLanne pranced through his exercise routines, most notably his fingertip push-ups.

His show continued into the mid-1980s. [and continued long after in reruns on ESPN Classic]
...
At 60 he swam from Alcatraz Island to Fisherman's Wharf handcuffed, shackled and towing a 1,000-pound boat. At 70, handcuffed and shackled again, he towed 70 boats, carrying a total of 70 people, a mile and a half through Long Beach Harbor.

He ate two meals a day and shunned snacks.

I remember watching as a child in the '60s. He was a man with enormous positive energy.
