I've thought about that, but I'm not sure it would specifically help the climbing problem--because one of the things I'm prone to do is think, "but if I just go for a run instead, I can be done and showered and everything in just an hour." So feeling like I have to report to someone that I've exercised is not quite the same kind of accountability as knowing that my climbing partner will be unable to climb if I don't show.

Mostly, it's just one of those mind over matter things until I get the habit re-established. And habit formation is supposed to take 6 weeks or so.
