I happen to know piles about bodybuilding
I did it for 15 years.
It's impossible to be a real bodybuilder and real pool at hte same time, it is possible to go to the gym and train and be fit and play great pool, Mika is a prime example.
Same for power lifting(not bodybuilding) the 3 lift discipline of powerlifting and pool dont mix.
Sux because I love both, I havent been able to body build since my beck went out in 05. Success in bodybuilding is much like natural talent in pool, to reach the top you have to be born with something special, no amount of roids will get a regular guy to competitive levels.
That's a whole other discussion, I can talk lots about training and pool. AQctually for a time I was a personal trainer(I'd fill in for my friends who had clients if they got sick or busy) i really enjoy training people. bodybuilding or fitness is what I know. Powerlifting I dont know a a whole lot about training for, however I have spotted (at the time the #1 powerlifeter in the world Anthony Clark) Just happped to be at the right place at the right time.
I end it here, but I love bodybuilding and it paraells pool in many ways.
I competed in power lifting competitively for a few years. I stopped doing it seriously but i still focus my workouts around the the big 3 and I am playing pool every night, it definitely does not affect my game because I am not getting sore doing high reps to failure. Powerlifting would have Less affect on your game than bodybuilding.
