I heartily recommend the r/bodyweightfitness's Recommended Routine (https://old.reddit.com/r/bodyweightfitness/wiki/kb/recommend...). I found it extremely reasonable, convincing, and beginner-friendly. It has detailed progressions on what to start from if you can't do a pushup or other (all the way up to if you can do it on one hand or whatever), and is absolutely not condescending, instead gives amazingly practical advice. It doesn't ask you to do more than 8 repetitions of any major exercise ever in a series, regardless how advanced you are, and there's whole ton of explanations why it's enough and why physiologically the freaking breaks between exercises are important and must not be shortened. I found it amazingly anti-bullshit yet super approachable.
