According to a neat little article over at Gamasutra, gamers make great bodybuilders. The reason for this is not that our superior thumb muscles give us a better grip on dumbbells, but rather the way our hobby has conditioned our brains to work. A lot of the concepts we use when we game translate rather readily to exercise. Finish a 30 minute jog? Quest complete. Add an extra plate to the barbell? You've leveled up. Monitor your food intake and watch your strength, stamina, and body weight fluctuate? Stat management.
I can see the connection pretty easily, and a friend of mine who got my lazy butt into the gym about a year and a half ago explicitly stated that working out, for him, was like a game. He would tweak his diet to get the most optimized results from what he ate and would adjust his routines when he would notice that, say, his biceps were progressing at a faster rate than his triceps, or his left leg was getting bigger than his right. Then we've got Wootini's weight loss and fitness journey with the Wii Fit, Nintendo's peripheral that takes the gaming mentality and applies it directly to exercise.
The article's worth a read and makes some interesting observations. What I found to be really fun was that they provided a link to a new site called Fitocracy. Like Wii Fit, it takes gaming concepts and applies them more directly to exercise, complete with levels, achievements, and challenges. It's not public yet, so you have to sign up and wait for an invite, but if you've ever needed some kind of external motivational spur to sign up at Gold's, then this looks like the perfect thing to take advantage of your gamer mind so that come June you'll be ready to suntan in a speedo.
