Yea, I was doing some research on “the Jet”. If you look at video of her from about 3+ years ago her upper body was deficient in any kind of muscle mass. Also, she was more girly. Make no mistake about it, she was still pretty fast.
Fast forward today, her upper body has made a CLEAR transformation and her personality is more masculine and aggressive. So from what I gather, JS does not play around, he makes sure is athletes hit the gym.
