Teresa really gets into it about ten minutes into the shoot, flexing and twisting her big calves on the stairs in all kinds of positions. See her make her calf muscles jump up and down as she puts her feet on the wall and pushes hard, and dig the silhouettes of her legs as she stands in the doorframe going up hard on her toes. She loves to feel the power in her legs and you will love seeing how distinct her calf muscles are.
