I'm terrible at sticking with a regular workout commitment, but I try to do whatever seems fun - and, most importantly, try to never turn down a chance to exercise (sports, workout, whatever) with friends, because that's always a lot more fun. Over the last two years, I've done: rollerblading, soccer, jogging, P90X, tennis, frisbee, golf (driving range), swimming. I'm far from good at any of them, and I do occasionally go for a couple of weeks or even months without doing much, but I figure every bit helps. Fun is the key - as well as doing as much as possible with friends. P90X is great for someone looking for a hardcore solution - it's hard, but it WORKS, if you actually stick with it (it's not a small time investment). I only did it for about a month, and I could feel the difference - now that winter's coming, I might start it up again.
