If you look very closely, the model does have wrists. (Most noticeable on the models left arm — that is the viewer’s right.)
Either way, the shoulder and elbow joints don’t move much during rope skipping, and no matter how it’s recorded, the motion capture data that was used for training should reflect that.
My best guess is that the model has picked up on the tiny arm motions that are present in rope skipping and wildly exaggerated them for some reason.
