Jack made headlines around the world for his accomplishments as a bodybuilder and for setting numerous world records for performing various death-defying feats of strength. At age 40, he swam the entire length of the Golden Gate Bridge underwater while carrying weights. At age 42, he set a world record of 1,033 push-ups in 23 minutes. "Anything in life is possible if you make it happen," Jack says.
Now in his 90s, Jack says he works out two hours a day, seven days a week. He says he also still lives by the two basic nutritional rules that have guided his entire life: "If man makes it, don't eat it, and if it tastes good, spit it out!"
Jack says his diet and exercise routine may be more intense than most people's, but he says average Americans can transform their lives by simply working out 15 to 20 minutes a day and by substituting more whole foods into their everyday diets. "It's not that difficult," he says. "You don't have to kill yourself—eat more natural foods, and I'm telling you, you can change your life."
