The challenge: do a handstand and put on a shirt while you're upside-down!

It all began with a simple challenge: do a handstand and put on a shirt while you're upside-down. But two participants have just taken it to a whole new level.

Tom Holland, aka Spiderman, got it all kicked off with an Instagram post. 

At the end, he challenged fellow superhero stars Ryan Reynolds and Jake Gyllenhall in a social media throwdown. One of them did it cheerfully, while the other, not so much.

Fast-forward a bit, and Olympic bobsledder and track star Lolo Jones threw her hat into the proverbial ring ... with a glass of wine on hand, no less!

Just for fun, Olympic gymnast Simone Biles added her own fun twist to the challenge, proving that it pays to be well-balanced.

Who do you think did the best job at #thehandstandchallenge? Sorry, boys, but I'd say that Lolo and Simone have it down pat!
