LOOK, NO HANDS!
There’s no telling whether this lady is sitting on a skateboard or a gym mat. One thing’s for sure though, she’s in her gym outfit and is doing what looks like a set of sit-ups.
And if it were true that she was actually on a skateboard, doing sit-ups on it while it zooms around is quite a remarkable skill — credits to her strong core for being steady while the skateboard moves around.
