This muscle lady got some very huge biceps on the left arm. I wouldn't like to arm-wrestle with the left hand.
This blog is about girl muscles, just as the title says. It is however not mostly about big muscle girls with huge biceps but rather hot teen girls with medium thick triceps. For arm-wrestling pictures, check the armwrestling gallery. A good female biceps resource is . The Valkyrie. Here are some armwrestling clips by the way.
