Braced Arm, Knee RestPose Reference

Both legs run out in front, close together, the knees only softly bent so the heels stay on the floor and the soles tilt up. The pelvis rolls back a touch and the torso reclines onto the figure's right arm, which is locked straight and planted behind and beside the right hip, wrist bent back so the open palm lies flat. That arm carries a real share of the weight and becomes a strut from shoulder to floor. The left arm crosses the body diagonally and rests its hand on the right knee. Because both hands pull to the same side, the shoulders swing toward the bracing arm while the head tips the opposite way, giving a relaxed counter-tilt at the top of the figure.

As a sitting arm braced behind hand on knee study, it rewards tracing three triangles: legs and floor, bracing arm and floor, and the loop of the crossing arm against the chest. The side view from the figure's left lays out the long diagonal of the legs and the recline of the back; the bracing arm shows only as a strut behind. The back view is where that arm reads clearly, angled out and down to its flat palm. From the front, the legs foreshorten sharply and the knees overlap the pelvis, so measure the shin lengths rather than guessing. The high angle explains how far the support hand sits from the hip.
