I walk every day 30 minutes from my apartment to my office in the morning, and then another 30 minutes back in the evening. I do it at a very fast pace. I would say I walk as fast as one can fast without running (passing people surely think I am late to an important meeting or something, I mean, it is really fast) and I also do it in the weekends.
Out of mere curiosity, I wonder if that can be considered aerobic exercise to a certain extent, and what can be the benefits I should reasonably expect in the long run. My body is fully adapted to that, I sweat very little or nothing at all, and I don't feel tired at all.
I wonder too, if that is enough cardio complement to resistance training, or if ideally I should try to introduce more aerobic exercise (I am 43). I swim from time to time too, but let's forget about it because I don't do it on a regular schedule yet.
