Tiger Woods has revealed what his astonishing daily routine used to be when he was at the peak of his powers after he was asked by his playing partner this week Justin Thomas.
The 14-time major winner, who changed the modern game of golf so drastically, is the inspiration for so many young golfers, including top professionals such as Thomas.
Arguably, the greatest golfer of all time, Woods was among the first to become an all-round athlete and the dedication he displayed each day was undoubtedly a key factor in his success.
Woods said: as per Golf Monthly: “JT (Justin Thomas) was asking me this on a flight, ‘what did you used to do when you were about my age?'
“Well, I used to get up in the morning, run four miles.
“Then I’d go to the gym do my lift.
“Then I’d hit balls for two or three hours.
“I’d go play.
“Come back, work on my short game.
“I’d go run another four more miles.
“And then if anyone wanted to go and play basketball or tennis, I’d go and play basketball or tennis.
“That was my daily routine.”
However, as impressive as that is, it is more than likely it such a vigorous regime has contributed to the severe injuries which have blighted his career over the last decade or so, especially with his back.
Unsurprisingly, Woods admitted: "I'm not doing any of that now."
Tiger's recent return to golf continues as he plays with Rory McIlroy and Thomas in a star-studded three ball in this week's Genesis Open.
The former world number one returns to Riviera for the first time since 2006 - a course that he has never been victorious on, in 11 times of trying.
Woods, Thomas and McIlroy tee off at 3.22pm UK time off the first tee on Thursday and then slightly later at 8.02pm off the 10th tee on Friday for their second round.
Despite not being able to train as extremely as when he was 24, all golf fans will be hoping that Tiger Woods can return to some good form and start competing for tournaments and majors once again.
