Eventually there will be a relevant and non-obtrusive text(?) based ad in the email.

There already is a Like link there...but that needs a little tinkering to get it to behave like I envisioned. Will need to add +1 since that's getting popular. Another one I've been contemplating is to add Twitter link as well.

I think your idea of turning this into a game like experience is brilliant. One thing I've noticed with emails of this nature is that after a while you start to ignore them. Letting readers keep score of the reps/tasks completed would hopefully entice them to keep opening the emails and, more importantly, keep them exercising.

And thanks for signing up!
