LaLanne's publicist, Ariel Hankin, said Tuesday that the 95-year-old underwent the procedure at a Los Angeles hospital on Dec. 8.
Hankin says that before the surgery LaLanne told his family, "I can't die, it would wreck my image."
The weightlifting guru is doing fine and expected to make a full recovery.
