Motion edit prompt

Keep the bench, torso, head, hips, legs, and feet essentially fixed. Animate the lifter’s arms, hands, and attached round weight as a linked rigid lever hinged at the shoulders: from the starting pose with the arms hanging downward, the arms travel upward and to the right first in a smooth arc, straightening out in front of the head with only minimal elbow bend. The hands and weight stay locked to the ends of the arms, moving along the same shoulder-centered arc; the circular weight and its small inner details rotate slightly with the hand as it rises. Move with smooth ease-in/ease-out timing into the fully raised position with the arms extended diagonally upward, then reverse the motion along the same path, lowering the weight back down until the arms and weight return to where they sit in the provided SVG, with a smooth controlled descent and no movement from the bench or lower body.
