HEY …IVAN…![]()
I read you are struggling with the back muscles…random and unpredictable…for sure not the case with any of the muscles in any living form…
They are always predictable, if you know thier FUNTION…ACTION/REACTION type of thing…allows for motion.
Those OPPOSSING CURVES on the old masters drawings and paintings are much more than just an effect that creates rythum in the figure, …they are the result of the muscles in the figure working at whatever funtion they are set in motion to create.
In the back area, you have pairs of muscles that allow for twisting, strecthing, standing erect, and leaning forward, to ultimetly touch your toes.
Along side and running parallel to the spine, are two muscles that allow you to straghten and bend…erectus muscles…next to them on ether side, are the major muscles that allow for the twist of the torso…latisimus dorsi…next to them, are the side muscles…which allow for pulling the upper torso to the side. The latisimus dorsi and side muscles work together to give a sideways pull of the torso with a twist.
Then you have your shoulder blade muscle groups, which allow for shoulder twist, arm rotation, elevation ect. Above those, you have your neck muscles which allow you to look up and down.
In the case of a twist, one muscle group will be stretched out, while it’s opposite will be compressed /pinched/shortened,…which in turn gives you an OPPOSSING CURVE.
If you look in Burne Hogarths book…DYNAMIC FIGURE DRAWING, you will see this princible of oppossing curves/ muscles working/ funtioning, to CREATE MOTION…
I took a class called Anatomical Drawing years ago…MUSCLE ATTACHMENT to bone/ MUSCLE FUNTION AS IT RELATES TO TO BONE MOVEMENT type of thing. If you ever see a class like that, and have the chance, take it. Totally different than a life/figure drawing class.
It’s a class that makes sense out of what you are seeing, so that what you see doesn’t seem random and unpedictable, and ends up making perfect sense…:bounce: 
KEEP UP THE GREAT WORK AND PROGRESS …IVAN, AND STUDY BURNE HOGARTH’S DYNAMIC FIGURE DRAWING BOOK…MOST OF THE ANSWERS TO WHAT YOU ARE SEEKING, ARE WITHIN THAT BOOK…
TAKE CARE
