Forget Charles Atlas. Forget Jane Fonda. Forget Arnold Schwarzenegger, Chuck Norris and that guy on the infomercials for the Gazelle Freestyle Muscle Toner. When it comes to exercise and fitness, there's one man who has had far more influence than any other. That man was Jack LaLanne.
LaLanne, who died on Sunday 23rd January 2011 at the age of 96, leaves behind an incredible fitness legacy. He is the man who invented cable machines, leg extenders and Smith machines. He's also credited with concocting the first meal replacement drink and the first nutrition snack bar.
He introduced millions of people to the star jump. And in the 1950s, when Jane Fonda was still in pigtails, he pioneered television exercise programmes, dragging thousands of overweight Americans off their couches in the process.
He also completed an astonishing number of formidable physical challenges, and we list some of his greatest hits below.
Thank you, Jack. Rest in peace.
