Accountability

I understand that you're looking for in-person or at least one-to-one support, so don't know whether any of this would suit you, but here a couple of virtual options within MFP you could consider:

1. Take a look in the "Challenges" part of the Community here, see if there are any challenges that are connected to your type of preferred activity, and join in. There are lots of different types of challenges, from a few days to a year, activity specific (bike or walk/run distances are only a couple of obvious examples) or general. That's here:

2. In the Exercise and Fitness area, there are a few threads where people share their workouts of the day, with more or less structure to the posts. These two are quite general, any type of activity:

I participate in one of those as part of my own self-accountability tactics. (I do think that the only real accountability is accountability to ourselves, but that sometimes interacting with others who have similar goals helps to keep that kettle boiling. YMMV.)
