Stefan Popovic completed nine one-handed rear delt flies on a selectorized gym machine in Calgary, Canada, at 310 pounds: the pin in the bottom plate of the 300-pound weight stack plus the machine's two 5-pound add-on weights. Seated facing the machine with his left hand braced in front, he swept his right arm out to the side and back for each rep, lifting the full stack and both add-ons off their rest nine times in one set. Review of the uploaded video counted every lift, three more than his earlier mark of six.
