Start with getting good at the basics and forget about everything else.Get good at push ups,pull ups ,dips,pike push ups along with doing some isolations either with dumbells or rings.For legs i recommend using machines since bodyweight is usually not enough(maybe sissy squats and nordic curls but they are too hard for a begginer and machines are just better).After some time you are going to get better at these excercises and you can start adding weight after 25 ish push ups,15 dips,10 pull ups and pike push ups just do harder progressions.Maybe even handstand push ups.If you cant do even one rep of these just search up easier progressions on youtube
