It’s really impossible to overstate the impact that Jack Lalanne, who died on Sunday aged 96, had on the fitness and exercise industry. Yes he invented the original Smith Machine, leg extension machines, the weight selector device and calf raise machines, all now standard equipment in any gym.

Yes he was talking about the importance of eating non-processed foods back in the 30s when most people still believed that smoking was good for you.

And yes, he is the guy who, to celebrate his 80th birthday, swam 1.5 miles, with handcuffs and shackles on, from the Queensway Bay Bridge in the Long Beach Harbor to the Queen Mary whilst towing 80 boats with 80 people on board.

But he was even more than all of that. He was someone who, in his own words, did all of that crazy stuff “to show that anything in life is possible. All of us can be much better than we are.” Jack Lalanne, we salute you.
