Tiger Woods single-handedly changed the face of sport at the end of the 20th century and turn of the 21st century. And not just with his golf clubs.
At the peak of his powers, Woods turned his slender body into one of the most ripped bodies in all of sport.
While some believe his compulsive attitude to the gym and lifting weights proved detrimental to his swing as years progressed, the transformation of his body was clear for all to see as he raced his way to 15 majors.
Woods' daily exercise routine from back in the day was recently published in the new book Tiger Woods, and as you might expect, it's all pretty intense.
Things may have changed somewhat today following a fourth back surgery last season, but Woods is evidently still pumping iron - as reflected by ranking in the top three for clubhead speed on the PGA Tour last season!
--- TIGER WOODDS ON HIS CURRENT SCHEDULE
Check out Woods' daily routine below, starting from the early wake up call, sometimes around 4.30am. Could you hack all of this in a day?
#1 - THE EARLY MORNING JOG
According to his former swing coach Hank Haney, even Woods' four-mile runs were cranked up a notch by him wearing combat boots.
Yes, four miles!
#2 - INTO THE GYM TO LIFT WEIGHTS
Manual Therapy: A system of extensive stretching (34 to 40 minutes before each workout) and manipulation/mobilisation of Woods' muscles and joints.
High-Rep Weight Training: This programme features higher reps (often 25 to 50) and submaximal weights, rather than the sets of 6-12 reps with heavier weights favoured by bodybuilders and others trying to add size
#3 - TIGER BALANCES HIS WORKOUTS WITH HEALTHY FOOD
Woods was pretty smart about what he ate while playing at his best. He kept himself hydrated with water and Gatorade out on the course, and stuck to a high-protein diet full of healthy carbs and fats. He fueled up perfectly and stuck with lean, heart-healthy foods.
#4 - TIME FOR SOME GOLF... APPROX 3 HOURS HITTING BALLS ON THE RANGE WITH HIS SWING COACH
Woods may have had a natural ability to play great golf, but he would still spend at least three hours hitting balls on the range.
#5 - MORE GOLF... 9 OR 18 HOLES
Time to put that practice into play on the golf course.
#6 - SHORT GAME PRACTICE FOR AT LEAST AN HOUR, MAYBE TWO
Probably explains THAT chip shot from Augusta National then.
#7 - TIME FOR ANOTHER RUN (SOMETIMES IN COMBAT BOOTS!)
Yup, another cheeky four miles.
#8 - END THE DAY BY PLAYING A DIFFERENT SPORT
No, not darts, but either some basketball or tennis.
