S.L. nice cut to the chase post.... glad the OP ster took it right.
To me pool IS a sport. anywho
In 76 on the hill in an event in S. CA, was worn out & rolled over in the finals.
I was in my late 20's

. WTF?

I was in the Olympic time trials, speed skating in my youth, the coaches always wanted you to work out/train.

Well 15 yrs later I listened

. to what they SAID but it took awhile

.... it works.

)))
Once I got in shape I could play 16-18 hrs straight, and when the sun was coming up, I played even better, room was quiet/calm/ air was clean and I was always ahead in those long match ups.
Beat Annagoni at Stoniers place in Sacramento CA in the late seventies because I was in shape, and Tony was in great shape I would of lost had I not of done my road work.
Tony, played good back then, but he strutted a little to much for my upbringing.
It was that yr 1976 that I started/created my workout routine.
5 days a week, weekends off.
I only run on level soft grass/soccer or football fields, NEVER concrete.
When I started in S. Cal. I ran off the beach in the soft sand, down by the Queen Mary in Long Beach.
The boys named me Long Beach Bill....
I only run 2 miles.... that ups my heart beat and strengthens my legs.
When I got to about 65, I do the exact same every other day, only 3 days a week.
Since then and even now, my trunk and lower body are good for 8-10 hrs of play, if I get my rest.
