To people of a certain generation, Bruce Lee - born Lee Jun-fan in Hong Kong in 1940 - is a revered figure. It is unlikely martial arts would be as popular as they are in the West - or that MMA would be the global phenomenon it is - had Lee not burst onto the silver screen in the late 1960s with films like Enter The Dragon.
Here's just one video capturing Lee at his best.
We seem on the verge of renewed interest in Lee. He will be played by actor Mike Moh in 'Once Upon A Time In Hollywood', the eagerly-anticipated Quentin Tarantino film on the last days of the golden age of Hollywood that is due out this summer. Cinemax's martial arts western series Warrior - based on a Bruce Lee concept - has also been renewed for a second season.
Fitness and nutrition were just two of the fields that Lee proved himself to be a pioneer. Lee's incredible physique and pliancy was the stuff of the legend, and Lee's biography, Bruce Lee: A Life by Mark Polly, captures some of the revolutionary diet techniques that Lee was using back in the 1960s. A lot of them are still valid today (others perhaps are more controversial)
Lee was one of the few people in the 1960s to own a commercial juicer. He was an early advocate of protein shakes and his favourite ingredients were "protein powder, iced water, powdered milk, eggs, eggshells, bananas, vegetable oil, peanut flour and chocolate ice cream."
Lee took his interest in power shakes to slightly-upsetting places, as the book claims he used to make shakes of raw hamburger meat. He also apparently when through a stage of only eating animal organ meat.
The kung-fu master aimed for 5 small meals a day. He didn't drink caffeine, didn't drink alcohol or smoke. He meditated regularly, added supplements like ginseng to his tea and used to run 4-5 miles a day every morning. 'It's my hour, every morning, where I can be alone with my thoughts'.
There's a lot fitness fans can learn from Bruce Lee. You don't get a physique like that without discipline.
