On the "rather not be seen" point, one hack that works for me is to exercise at night or the very early morning. For a long while I would go running at 4:30 or 5am when the streets were mostly still empty. I also found a 24 hour gym and started identifying times when I would be the only person there. (For me, it's not that I don't want to be seen, but I felt less anxious without anyone else around, and it also meant I could use any equipment I wanted.) But even solving that point, I still struggle with the motivation & enjoyment. The 24hr gym has got me working out more, but still not regularly.
