Here's a list of aerobic activities in which I engaged in the early and mid weight reduction stages:
1 - Elliptical trainer
2 - Swimming
3 - Biking
4 - Ice skating
5 - Walking/hiking
Notice that running doesn't appear on the list. From the moment I shied away from running, some thirty pounds ago, my joints thanked me. All of the above, in addition to some key steps involving diet and stress management, allowed for a sustainable drop in weight. I did not begin running seriously until dropping into the mid 180s, from a starting point of 209 pounds in early 2009.
