Forearm: Tho I don't struggle much with it anymore I would like to see the motion, deformation of mass and interaction of the branchioradialis with the branchialis, biceps, the elbow joint (how it slides over the humerus/ulna while they bend and twist) and mostly how it's thickness affects this interaction.
To elaborate, most of the useful reference one can find is of massive forearms. This however makes it unclear how thick this muscle gets on all sides, thus making it confusing to predict how it will interact with the underlying bone and the surrounding muscles. I've deduced that this muscle is pretty slender and slim initially, and while it grows much, a lot of that mass (which also contributes to the intense line created that separates it from the flexors) is built externally (not on the internal side that can touch the biceps when curling) and due to it sort of riding the point where the radial bone meets the humerus bone, but this isn't easily understood on a thin model because the muscle is non-existent and the muscularity of a large model hides the bone evidence. I'd just like to see if my suspicions are correct.

Hi Proko! Would like to know how the forearm muscles change as they contract and others relax in their different positions (e. g. with radius over the ulna, and forearm flexed with hand turned inward and then upward, then twisted back wth same positions, and if the specific muscles can be highlighted. The twisting motion of the radius and ulna and how the muscles are affected would really help me.

I would like to learn in the next lesson how the flexor and extensor muscle groups appear in back view. I struggle with how those groups appear when the arm pronates and supinates from the back as well as the sides! I know the extensor groups are supposed to follow the the thumb but I just can't visualize very well when the groups seen from the back. Thank you so much as always for the lessons! :)

Please spend more time covering foreshortening. So for example in dynamic poses you when the arm is coming right at you, you could cover how to judge the muscle over laps, in particular at the joints. Thanks Proko. For the money you charged, I'm genuinely surprised by how much I am receiving. Are there any books you recommend to supplement your course?

Studying the arm from Burne Hogarths book but having trouble trying to synchronise what I know with other sources. Some info on (1)what muscles supinate and what pronate - not sure if flexors and extensors play a part. (2)abduction and adduction muscles? (3) order of muscle overlapping. Sources differ on what muscles overlap what. Love your vids -

I would say it is important to learn what effect the movement of the hand has on the over all form of the forearm. That would be the biggest thing I really want to learn. Also the anatomy of course, but you do that really well already. I like the more dynamic elements you are adding into the videos. Keep up the good work Stan. I love your stuff.

perhaps it would be best to have multiple videos explaining the forearm? We can see how the flexors and extensors function or behave as a group when the arm twists, then explore the muscle groups in detail in other videos?

If im honest what I would like to see after you're done with the muscles in the arms is to perhaps draw them in different posses and perspectives.
