Sam Asghari has posted a clip of himself pumping iron, while girlfriend Britney Spears cheered him on. He hit the gym in a grey tank top and grey, army-printed shorts while burning through a set of bicep curls. “Squeeze! Pump iron! Do all those things to make all those veins come out. Sexy man,” Britney was heard saying from behind the camera, as Sam broke a serious sweat.
