Might I remind you he is the reason why bb'ing is what it is. He beat Arnold in an informal competition at the age of 54 years old.
Here is a C&P of Jack Lalanne's accomplishments from age 40 on as an example that he could have done double this in his prime and before the age of 40.
1954 (age 40): swam the entire length (8,981 ft/1.7 mi) of the Golden Gate Bridge in San Francisco, under water, with 140 pounds (64 kg; 10 st) of air tanks and other equipment strapped to his body; a world record.
1955 (age 41): swam from Alcatraz Island to Fisherman's Wharf in San Francisco while handcuffed. When interviewed afterwards he was quoted as saying that the worst thing about the ordeal was being handcuffed, which significantly reduced his chance to do a jumping jack.
1956 (age 42): set what was claimed as a world record of 1,033 push-ups in 23 minutes on You Asked For It,[31] a television program hosted by Art Baker.
1957 (age 43): swam the Golden Gate channel while towing a 2,500-pound (1,100 kg; 180 st) cabin cruiser. The swift ocean currents turned this one-mile (1.6 km) swim into a swimming distance of 6.5 miles (10.5 km).
1958 (age 44): maneuvered a paddleboard nonstop from Farallon Islands to the San Francisco shore. The 30-mile (48 km) trip took 9.5 hours.
1959 (age 45): did 1,000 jumping jacks and 1,000 chin-ups in 1 hour, 22 minutes, to promote The Jack LaLanne Show going nationwide. LaLanne said this was the most difficult of his stunts, but only because the skin on his hands started ripping off during the chin-ups. He felt he couldn't stop because it would be seen as a public failure.
1974 (age 60): For the second time, he swam from Alcatraz Island to Fisherman's Wharf. Again, he was handcuffed, but this time he was also shackled and towed a 1,000-pound (450 kg; 71 st) boat. At least that's according to his website. However, according to an account of this event published the day after it occurred in the Los Angeles Times, written by Philip Hager, a Times staff writer, LaLanne was neither handcuffed nor shackled if each of those terms has the unconventional meaning of "tightly binding the wrists or ankles together with a pair of metal fasteners" although that's not how handcuffs or shackles work. Hager says that LaLanne "had his hands and feet bound with cords that allowed minimal freedom". But "minimal" clearly did not mean "no" freedom, since elsewhere in the article Hager describes LaLanne's method of propulsion through the water as "half-breast-stroke, half-dog paddle" which is how you swim with your hands tied.
1975 (age 61): Repeating his performance of 21 years earlier, he again swam the entire length of the Golden Gate Bridge, underwater and handcuffed, but this time he was shackled and towed a 1,000-pound (450 kg; 71 st) boat.
1976 (age 62): To commemorate the "Spirit of '76", United States Bicentennial, he swam one mile (1.6 km) in Long Beach Harbor. He was handcuffed and shackled, and he towed 13 boats (representing the 13 original colonies) containing 76 people.[32]
1979 (age 65): towed 65 boats in Lake Ashinoko, near Tokyo, Japan. He was handcuffed and shackled, and the boats were filled with 6,500 pounds (2,900 kg; 460 st) of Louisiana Pacific wood pulp.[33]
1980 (age 66): towed 10 boats in North Miami, Florida. The boats carried 77 people, and he towed them for over one mile (1.6 km) in less than one hour.
1984 (age 70): handcuffed, shackled, and fighting strong winds and currents, towed 70 rowboats, one with several guests, from the Queen’s Way Bridge in the Long Beach Harbor to the Queen Mary, 1 mile
