"Whatcha gonna do, sister, when Samantha Stosur runs wild on you??????!!!!!!!!!!"

The 30-year-old Australian tennis star displayed her (guess-timate) 24-inch pythons to the home crowd during Day 2 of 2015 Australian Open Tuesday and those biceps looked bigger than ever.

Believe it or not, Stosur swears she never does biceps curls in the gym. Hammer curls? Anything? That can't be straight from the old Rickey Henderson workout of push-ups, sit-ups, running and talking in the third person, can it? It just doesn't seem natural.

"I don't spend that much time lifting weights," Stosurtold ESPN The Magazine in the spring of 2014. "I never do biceps curls, and I very rarely do bench presses."
