Michelle Jenneke
Michelle Jenneke briefly took over the internet with her viral warm-up dance prior to a race in 2012. Jenneke, a hurdler, has a pre-race warm-up routine that involves a giant smile, and vigorous shaking of the hips.
It’s likely that Jenneke never would have achieved the fame that she has garnered without the routine, as she was never at the top of her field. She did qualify for the 2016 Olympics in Brazil but finished in 37th place. She’s still competing but has parlayed her fame into a modeling career as well.
