Lydia, after a frowningly intense inspection of the pommel horse and a quick google that told her she would absolutely not be doing that (although she might be looking up some more videos of men's gymnastics later, for educational purposes), used the pommels to boost herself up so that she was sitting sidesaddle on the horse between said handles, and gave a little 'ta-da' gesture with her hands and a big smile like she'd actually done something here.
