I would honestly have to say that I check out other guys more often than anything else. I check myself out in the mirror, but I can pretty much expect the same thing from day to day. I definately check out the womens, because they are so hot and their bodies are perfect... but I feel like a pervert if they catch me looking. Looking at other guys however, is good to get you motivated. When you see some dude with 20" pythons and a huge chest, benching 300+, it definately gives you something to look forward to or to at least make you strive for it. I always check out other guys to see how I could improve myself.
