<p>Amother, here is another suggestion for beating the "stereotype" - look into Scouting in your community. He is a little old to start, but a friend of my daughter's joined a regular, but very well-organized and active troop in ninth grade, and actually made Eagle before aging out, so it can be done by a determined kid.
Scouting is not an academic EC, gives leadership training to kids who wouldn't otherwise ever get it, and in good troops, has lots of exercise and outdoor activities. If regular Scouting is not his thing, there are Venture troops now that do more specialized activities.</p>
