I knew her and her partner well enough to know she really didn't touch any gear. She literally trained constantly, ate perfectly with world class support and trainers. She was a powerlifting champ from teens through college.
Now to my main point, I worked out regular with a woman with amazing genetics (her parents were unbelievable fit athletes). The look and leaps suddenly as competition was getting closer in ways that didn't make sense. It was clear that the ones going to the games (certainly after 2015) were on shit. A number of pro athletes and even actors from Marvel films trained there as well.
I was very into crossfit for years and was at a "box" that trained a number of people to the games (oddly enough most were affiliated with other boxes, for instance a lot of international CF folks came but remained affiliated in their home countries).
