for me, bodybuilding is a way of life (and it did change my life a lot)
reminds me all the time to keep on pushing and never give up, just keep fighting with patience and results will come ..
Lol, I used to know a boxer who would shadow box ANYWHERE waiting in the queue at the bus stop, choosing a DVD at the store.. You name it!
Why'd I say this? Because this is the kind of commitment you need to excel at ANY sport. A bodybuilder is someone who has that kind of dedication to the sport (and lifestyle) of bodybuilding. I don't see bodybuilding being different from any other sport in that respect.
