I've gotten pretty used to it. I have a big build so its obvious I work out a lot. People are also used to how much I eat at this point. It doesn't stop the comments though. It is basically everyday many many times per day. At work, at stores, wherever. People feel inclined to ask me questions who normally wouldn't talk to the person next to them in line at the grocery store. They will look at me and immediately ask "how much do you bench?" "do you play football?" "which team do you play for?" I don't really take too much issue with it but it does get a little old to have people ask you if you use steroids, accuse you of using steroids, or spread rumors that you use steroids. It also gets old when people attribute your dedication to something, like working out a lot, to being a "loser" or "filling up your pathetic life." I've had many people online somehow try to put a negative spin on something that is 100% positive. It's rather odd.
To an extent though, you have to realize that if you are really really into personal fitness then you aren't in the majority therefor you aren't "normal." Especially somebody like myself who weighs twice as much as most people on the planet and eats 5-8k cals per day average. That's just not normal and maybe I am a weirdo for it. But hey, atleast its fun and gives me stuff to talk about with random people. It really is a great ice breaker and has gotten me a LOT of contact with people and life is all about who you know. Hell it got me my current job..
