Simone Biles has been setting the bar impossibly high since she first came on the international stage in 2013.

In her Olympic debut at the Olympic Games Rio 2016, she won five medals, four of which were gold. Then, she took a step back from gymnastics for almost an entire year.

In 2018, she came back with a vengeance. She became the first female gymnast to win all five U.S. all-around titles in her career and the first since 1994 to win the all-around and four event titles at a single nationals.

At that year's world championships, she went straight from the hospital, where she dealt with a kidney stone, to the mat. She left worlds with a record-tying 20 total medals and as the first woman to win four all-around world titles.

There's no question that Biles is not slowing down yet.

Here are 22 photos of the gymnastics standout in honor of her 22nd birthday.
