It started with an innocent Tweet.

JasonFalls Wife and I are discussing a family YMCA membership. Could it be that I might start exercising? Stay tuned …

And, after a couple of responses, I threw this out there:

JasonFalls If I, Mr. 275 pounds and no exercise since 1988, will commit to a consistent exercise program, I want 50 followers to do the same. Takers?

Never understimate the power of your Twitterati. As of 10 p.m. ET Monday night, just five hours after calling on takers, I counted 28 different folks who either said, “I’m in,” that they’re already involved in a fitness goal but are with me or wanted to lend support in some way. Several others chimed in to say, “You go!” or offer other insights or suggestions.
