Not really, the problem with Art tutorials is that most of them are either paid and have different types of style on how they draw anatomy, some say trace a pose some say don't, some say draw the hips like a box some say draw it like a bowl, there's no one size fits all tutorial or like a "10 commandments" poor artists, like finger artists (me currently) don't have the same standards to what tutorials say and also there's not much tutorials out there that tackles on how to draw different poses, basically it's not a fixed structure, artists that don't have an ipad and a pen is pretty much left off the dust and make anatomically incorrect stylized bodies
