I think the conventional wisom is diet is more important than exercise in losing weight, although I think most people would recommend working out once a week regardless if you would lose weight or not, basically any working out would be positive if you aren’t at all, it couldn’t hurt to do sit ups and push ups and see where that takes you.

I would just make a substack or a self hosted ghost website unless you’re really invested in the development process.

I would just look at sites like https://apnews.com/ or https://www.bbc.com/ and see what they do, but I don’t think you technically need anything, plenty of people have wordpress blogs and substacks without a legal section. What’s the difference between your website vs a twitter account vs a substack where you live, probably not very much.
