At 66, the superfit grandad still does 200 press-ups EVERY DAY, 1,000 sit-ups per week and is only half a stone heavier than his playing weight.
The Hammers' greatest all-rounder played in the top flight until he was 41 and clocked up 793 appearances in claret and blue before retiring reluctantly in 1988.
Bonds told The Sun: "If I could give Ryan one piece of advice it would be this: ‘Play on until you drop’.
"You won't half miss it when you can't play anymore. I tried my hand at coaching and management afterwards and trust me, it's no substitute.
"I always remember my old boss John Lyall would come to me every summer and say 'I suppose you want another year Bill?' Without thinking I would say 'yes'. No question about it.
"Your fitness you can keep. Your stamina actually improves as you get older but it's your pace that fades. I watch Giggs and he still has it though. He's remarkable.
"I was 40-odd and played against Gazza when he was 16. He made his debut against us. That's when you realise your body is struggling to keep up.
"But above all that, you also need to enjoy it. That's the most important thing. Giggs has Champions League medals, Premier League medals, he has won everything.
"I was struggling against relegation most years. We were dangerous occasionally in the cups but usually West Ham were up against it in the league. But I loved it, every single minute.
"I look at players like Mario Balotelli and see the scowl on the face and I wonder why he bothers? But Giggs seems to love it more the older he gets.
"I don't envy him his medals, I don't envy any modern player their wealth either. What I do envy is their youth. How I'd love to be able to be young again and go out and do it all over again.
"The thing about Giggs is that he has also done this at one club. No one seems to stay very long at a club any more. That makes it even more laudible."
