She looks like she has been hitting the gym

Stacy enters the empty gym and walks up to the ring. Her long blonde hair conceals the sides of her face and her piercing blue eyes don't even acknowledge your presence. The rest of her body is concealed by a robe, which she immediately sheds after entering the ring. You couldn't believe your eyes! Every inch of her body was toned muscle. Her calves, thighs and ass were most notably firm and well shaped. Her core had the light outline of an 8 pack, her D-cup breasts were held firmly in place by her blue sports bra. Even her arms seemed much more defined. You studied her closely as she entered the ring and couldn't help but to wonder if she was more muscular than you and what other things she might have done to prepare for the fight. She looked up at you with a cocky smile and asked "ready punching bag?" Then entered the middle of the ring to start the fight.
