Britney Spears doesn't work out like the rest of us--she does it however she damn well pleases.
Take this Instagram video, for instance, in which the 34-year-old pop superstar hits the treadmill while pumping two barbells on Saturday night. And she does it all while wearing a bikini top and some dangerously low-slung pants.
“After Cheesecake Factory you do this,” Spears captioned the captivating clip. “Treadmill and weights.” Sounds good to us, Britney.
