Figured I'd start very simply:
Do my bodyweight training Mondays and Fridays (doing the thing is enough. no need to add yet)
Doing pretty well so far. Did my bodyweight training, today's not a work day, haven't snacked, already got 20/30 min down so a nice stroll with Bard later will top that up.
Been keeping track of my habits with HabitBull. It's a great little app and completely free if you only want to track 5 or fewer habits.
