Reference for the figure under load. Twist through the torso, the stretch and compression of opposite sides, push-off and landing — the mechanics that make an action pose convincing rather than merely energetic.
An action pose fails for mechanical reasons, not stylistic ones. The torso does not twist, the weight has nowhere to go, both sides of the body are doing the same thing. Dynamic Figure is reference aimed at those specific failures: the body under load, where the forces acting on it are visible in the form itself. The subject
Movement with force behind it — pushing, pulling, twisting, reaching, driving off one leg. What distinguishes these from ordinary poses is that they cannot be held comfortably. A body under load is being pulled out of shape by something, and drawing it means drawing the something as much as the body. What you'll practice
Twist and counter-rotation. The ribcage and pelvis are two solid masses joined by a flexible column, and almost every convincing action pose separates their angles. Learning to see the degree of that separation, then to exaggerate it deliberately, is probably the highest-value single lesson in action drawing.
Stretch and compression. When a figure bends or twists, one side of the torso opens into a long stretch while the other gathers into a short compression. Drawing both sides as symmetrical curves is what makes a pose look inflated and lifeless. This is where you fix it.
Foreshortening under pressure. Action drives limbs toward and away from the viewer. You get overlapping forms, compressed segments and size relationships that look wrong until you commit to them fully. Reference is the only way to build the confidence to commit.
