> What keeps fit people going to the gym on a regular basis isn't wearing their running shoes to bed at night. It's discipline and accountability. There is an alternative, less resistant path which I believe is more sustainable and better for the soul... find something you love that involves exercise, not much discipline is needed once you do, because you probably wont be able to stop yourself from doing it when it's…
For me (also an unsporting nerd who came to exercise in midlife), having less control is actually a benefit: because I've got a booked timeslot with my PT, I have to go or it's embarrasing as well as a sunk cost. If I give myself control over when I go it's too easy for it to be mañana. Pre commitment is a real thing.
