When I'm in the mood to be tied to a machine, I do use elliptical. I like those.

Swimming really wears me out. That's probably a good reason to do it more often...but I'm afraid I've been out of practice for so long with the various strokes that I just don't do it efficiently.

I really want yoga to be my thing. After failing as a weight lifter and a runner, I figured it best to use the talents I already have to open the door to fitness, rather than come at it with just my weaknesses. I'm naturally flexible and graceful, which has served me well learning yoga. Plus, since I'm naturally lazy and short on time, I like how yoga kills several birds with one stone--flexibility, strength, meditation, balance, and sometimes cardio (if I have a particularly vicious instructor leading a class) all in one session.
