I've never been one for the gym, jogging, running or swimming endless laps in a pool to get nowhere. I've always had to get my exercise from some game or activity that provides some sort of distraction. Paintballing is the latest but before that it's been tennis, windsurfing, bicycling, chasing my model airplanes (more later), both cross country and downhill skiiing, hiking and other things where the exercise is just a side benifit. But if I'm doing something JUST for exercise I find it repititive and boring and won't do it for anywhere near as long as it needs.
Unfourtunetly the other sports and activities tend to cost more than a simple gym or pool membership... They sure are a lot more fun though...
Chasing my model airplanes you ask? That's because one of my more favourite forms of model airplanes are free flight models. In this style there's no radio and no control lines. We just crank up the rubber or the engine and let 'em go. They are trimmed to fly in circles and we try to put them up into air that is rising to achieve our time goal of 3 minutes. After that a fuse or timer trips the tail to spring up at a crazy angle and the model sort of "parachutes" down so we can get it back. This is all great until windy days where the models can fly up to 1/4 to 1/2 a mile away quite easily. This style of flying needs to be done out on farm country for obvious reasons.
Here's a shot of one of my rubber models built from a prewar design. This one has a 3 foot wingspan.
