gymnast

A gymnast is someone who does acrobatic exercises or performs athletic feats that require balance and strength. They often compete in events like the Olympics.

Gymnasts are usually what people think of when they hear "gymnastics," but actually, the word can also refer to the sport itself, a type of exercise class at a fitness center, or even just someone who practices gymnastics for fun. But if you're talking about someone who's really good at doing flips and landing on their feet, then you're probably talking about a competitive gymnast.
