I maxed out the 200 sit-ups app, and now I use the 100 pushups and 200 squats apps on alternate days and do 200 situps when I wake up and before bed.

I'm using beeminder to tally the number of 20 min Pomodoros I do per day

I have a 7 day calendar with all my repeating daily or weekly tasks on it (the situps etc, putting up a blog post, retagging 5 posts on my blog from before the migration that lost the tags, checking on Mint on Thursdays, attending Krav and aikido class, etc). When I do a task, it gets a dot, when I miss it, it gets an x. Days with no x's get a happy face. On Monday, I count up the number of dots and log it in beeminder.
