Evelynn has many workout methods most of which involves putting more effort into her real muscles than her nano-enhanced ones but sometimes she likes to cheat and puts both of them through the gauntlet of intense reps. She can use that data to really see how her creation can put up with such extremes. Who says a scientist like her can't pump hard and make it all for research? Also yes, those are weights on her wings and her wings are folded. You got to just to keep a body like that airborne.
