Motion edit prompt

Starting from the current lowered press pose, animate only the two arms, hands, and attached dumbbells. Rotate each upper arm from the shoulder while counter-rotating each forearm from the elbow so the elbows unfold: the dumbbells lift away from the chest, first moving upward and slightly toward the feet/right, then curving back toward the head/left into a high position above the shoulders with the arms nearly straight. Keep the rear arm and rear dumbbell slightly behind and offset up-right from the front arm, while the front dumbbell remains visually in front when the weights overlap. Hold the fully extended position briefly, then reverse the same rotations and arc so the elbows bend and the dumbbells return exactly to where they sit in the provided SVG. The circular plates should track the hands without independent spinning, and the bench and the rest of the body should stay steady.
