However, this time she managed to do it while training ahead of the Olympics.

The gold medallist became the first woman to land a Yurchenko double pike vault in May this year.

She proved her gold medal prowess again today by casually nailing it in training.

Biles will compete for the US in the vault, uneven bars, balance beam, and floor exercise fields, as well as the all-around field at the Tokyo Olympics.
