He is waist deep in water, sculling with hands covered in black webbed gloves that look like something out of "Creature From the Black Lagoon." "These are Jack LaLanne hydronastic gloves!" he shouts, carving arcs through the water, pulling the gloves front to back and then back to front. "I pull with all of my weight,'' he announces dramatically. "It works your biceps, your forearms, your obliques. I've been doing this since I was 16." At 60, he swam to Alcatraz handcuffed. As he turns 90, LaLanne has his eye on Catalina Channel. He says his next stunt will be to swim 22 hours underwater (with air tanks or a hose to the surface) the 26 miles from Catalina Island to Los Angeles, a claim that is met by skepticism.
