I’ve been injured and sedentary too long. A couple of weeks ago I started walking along the bus route until it hurt too much, then hobbled onto a bus back home.
Today I made that distance and back with low/manageable pain.
Next time the same route will be less pain, and soon I’ll try going as far as I can in the other direction and bus back again.

Thank you! Yeah, it can be hard to assess the halfway point beforehand, and I have both bad days and good days (I didn’t make it all the way home today, but it was still good), so having transport nearby means I can attempt to go further.
