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.

That’s amazing, congrats! Every day you go for this walk is a victory
Thank you! I don’t do this every day but like 2-3 days in a row, then 2-3 days without. The rest days are more mental than physical, I think.
