So I've been trying out https://www.future.co (similar coaching concept for fitness).
While I really like the concept (esp since it means I don't need to make my own workouts, which was often an excuse I used not to workout) I haven't found the accountability aspect very effective, I was at it for a few months and then dropped off, despite the daily "YOU GOT THIS!!" text from a stranger on the other side of the country.
It's entirely plausible that at the end of the day I'm just lazy/not motivated enough and no amount of accountability will be helpful, but I wonder if there's a better form of accountability, particularly through likeminded social circles, you could integrate.
Just riffing (using workout as the habit, since I will absolutely pay big $$ if something gets me to work out more, future is $150/m);
1. Social shaming
a. the app notifies a bunch of friends every time you miss a workout.
b. I pay for someone to blow up my phone / texts ad infinatum at a certain time until I'm in the gym's geofence.
2. Material loss
a. you use Plaid to pull $XX out of my account and send it to my buddy every time I miss a workout.
b. set aside some large amount of $$ like $1000 and if I don't get to the gym 20x in a month, confirmed by a third party, the money is gone forever.
3. Material gain;
a. join a group of friends; y'all put $100 in a pot, add 1 point for every workout and subtract 3 points for every miss. When the squad hits 100 points you spend the money on a trip to Fogo de Chão. If you go below 0 the money is gone forever.
b. partner with gyms & give a 40% membership discount if the person has a rolling 15 days / month attendance.
