- Get really into walking. No matter what sport you take up, or any at all, this will still be the most important element as it lets you "warm up" and keep your body in a 'ready to be active' state as well as passively burning energy.
So be exploring parks around you, maybe get into photography to help have a reason to take walks.
People can lose all the weight they need to just from walking. It is also considered by some people to be essential for recovering your body from pain after a day where you worked out.

However, also get into calisthenics. This is solo exeercise designed to not need equioment or only lightweight equipment, therefore you can circumvent going to a gym for it. You'll want enough space at home or in a park to do it, and this is why many people do choose to do it at gyms anyway.

Pickleball or table tennis might be good sports to get into if you don't like team sports.

Swimming. I need to do more of that. It's acessible and "hidden away" from prying eyes.
