Long story short beeminder only works for me if I absolutely cannot cheat. Russian Practice is the only goal I still have going, because if I don’t complete a lesson in Duolingo, I will be charged.
I want to make the same thing for a biweekly workout goal. I thought about using IFTTT to force me to go to the gyms location, but it’s right across the street and I think my drive to work might trigger that.
Instead hook up a bluetooth enabled heart rate tracker to Beeminder and beemind you having a heart rate > x for at least y minutes z times a week or something stupid like that.
I don’t know if there is an integration that can do that, maybe Strava?
I don’t actually recommend doing this but then again this might in fact work.
