1956 (age 42) – set what was claimed as a world record of 1,033 push-ups in 23 minutes
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.
