Actually, I am going to do something different with this.
We need exercise; there's no getting around it. Throwing non-competitive exercise routines may help make gym a little more tolerable for us. Maybe petitioning to get a DDR arcade cabinet or two installed in your gym would help out with this; maybe assorted martial arts or fencing or archery could be adapted from their college settings to a manner befitting high-schools. Alternately, some schools give you the option to take weightlifting instead of gym, meaning the class is based on individual rather than team exercise.
As for bullying...I never really experienced it or if I did I never really noticed. Maybe it was because I'm relatively tall, or maybe it's because I was friendly or maybe it was because people thought I had the potential to set off another Columbine, who knows? Chances are you're not as lucky as I am so you are probably going to want to look for another group to take you in as its been mentioned before that bullies target individuals. Notify teachers about people bullying you.
You could always smart-talk to taunters that call you a nancy boy. After all, programming is far more homosexual an activity than involves having 20 buff guys dogpiled on you, then going to the locker room to pat your football teammates on their asses before going in for a steamy group shower. You have same problem with wrestling (though mudwrestling or jello-wrestling females are acceptable, as long as the women involved are hot). Besides, who needs football when there's Halo 2 (this game is unusually popular among jocks). It's amazing how FPS games have gone from being the plaything of social outcasts (Doom and Quake) to being a mainstream activity.
One warning; fighting unfortunately doesn't work, at least in school. Zero-tolerance policies now mean that the bloodied victim is just as guilty as the bully that tore him a new one. It's part of an attempt to teach kids never to fight and to be docile sheep. However, as long as you're not actually caught fighting (e.g. it takes place in a back alley) then you can get off scot-free. If all else fails (and even then you should take my advice with a grain of salt), you could always buy a ski mask and some knuckle dusters, drag this jock out of his current underage drinking party, and beat the living s**t out of him. If you need some heavier ordnance, try setting up a dummy corporation under a false name and purchase riot gear from a legal supplier (like alpineco.com); if you're strapped for cash, you can always go to your local hardware store to get materials for a good tower shield (it should be wood gets the job done), and a lead pipe wrapped in barbed wire or a crowbar (if it worked for Gordon Freeman, it will work for you) will make an effective bludgeon. Remember, the point is not to kill, but to brutalize your tormentor so much he won't ever consider beating you up again as long as he knows but can't prove it was you. So this means you should dispose of all evidence; burn the mask and shield, and dispose of the crowbar after using citric acid to remove your fingerprints from it. When trial takes place and there are no witnesses to testify, or evidence to be used against you, you get off scot-free and his family has to pay the court costs, adding insult to injury.
