Never felt it was. I am natural and do it for a challenge to myself...to feel healthy and look better. When I competed I never felt like I was missing out on things. Didn't care for clubs or drinking etc anyway so was happier to be in the gym. I have no regrets.
Probably no more of a waste of time than anything else that doesn't include conceiving and raising offspring.
Yes. I'm addicted to it, but I feel like it's a waste of time pretty often. Especially as a natural. The only thing really making me think its not a complete waste of time is, hopefully, maintaining my health well past retirement.
No. I train 2 hours a week. You chumps spend more time masturbating.
