Great post Spyro. You allude to it in your post, but if I may expand on it a bit, doing aerobics does not increase lung capacity or even lung efficiency. Both of these are exactly the same in a sedentary person and a fit person. What is dramatically different is the ability of your muscles to absorb and use the nutrients in your blood quickly and efficiently (primarily oxygen). This is what gets "trained" when you do aerobics. Not really anything earthshattering, but I thought it was an interesting fact
My only 2 caveats with aerobics are 1, impact, and 2, intensity. For impact, it's best to do something other than jogging. The eliptical machine, bicycling, swimming, fast walking, all are much better on your joints, tendons, and ligaments, and all give you very good results. For 2, aerobics should be easy to moderate intensity. The harder you push youself on aerobics, the more it will cut in to your recovery ability. Personally I think 3 times a week of easy to moderate aerobics is entirely do-able.
