LaLanne, who became US television fixture in his close-fitting jumpsuit starting in 1959 and came to be regarded as the father of the modern fitness movement, succumbed to pneumonia following a brief illness at his home in Morro Bay, along the California's central coast.

"He was surrounded by his family and passed very peacefully and in no distress ... and with the football game on Sunday, so everything was normal," Yvonne LaLanne, 66, told Reuters.

She said her father had remained active until a few months ago, including the taping of a recent public TV special. Well into his 90s, LaLanne exercised for two hours a day. A typical workout would be 90 minutes of weightlifting and 30 minutes of swimming, changing his routine every 30 days.

He preached the gospel of exercise, raw vegetables and clean living long after his contemporaries had traded in their bicycles for nursing home beds. "I can't die," LaLanne would say. "It would ruin my image."
