I remember we already talked about it -- similar journey. I ate trash when I was younger, same as almost everyone who was not already a serious athlete in school. Got health problems after mandatory military time. Got depressed, then decided to "weaponize exercise against my own self-destruction." I now lift three times a week, soccer once, golf once. Some people do not count golf. Roughly five days either way.
And the very important part no one talks about: gym and team sport are also how you meet new people as an adult who are not from work. New friends, actual community, connections that are not your business or job.
