Hey, TD! What a lucky guy he is - no "training"! cool. I think there's some genetics at work there...and once you reach a pretty high fitness level it doesn't take a whole bunch of work to maintain it.

I figure there's just three things that are truly necessary. Whatever you do needs to challenge you physically - it needs to be a good enough workout to give you a result.
Whatever you do you have to really like! If you don't like it you're not likely to do it enough to make a difference!
Whatever you do, you've got to change things up every once in awhile to keep your muscles working differently, once again to keep them challenged.

I'm going to try Pilates this weekend - got a free DVD in a box of cereal! And, if this weather holds, we'll have a light fun road ride on our mountain bikes on Sunday afternoon. (our roads are bad enough we almost want the mtb's even in great weather, but right now there's a lot of winter gravel, sand and schmutz on the road, so those skinny road tires would be lethal!!) Should work well to release the tightness in my legs from kickboxing! <grin>

Just get to it, everyone! Pick your fun activity, and keep fit!!

Wahoo and namaste,
~T~
