Teammate and fellow gold medalist Aly Raisman also makes her debut with Biles in the magazine's 2017 edition. Both gymnasts donned sleek black swimsuits, with Biles posed upside-down, masterfully holding a handstand, and Raisman draped over a bench.
Photographer James Macari shot the gymnasts at the World Champions Center in Spring, the North Houston Skate Park and the Lillie and Hugh Roy Cullen Sculpture Garden, also in Houston.
Next month, both women will also headline Vibes, a two-day music, food and cultural festival in Houston that celebrates the launch of the Swimsuit Issue.
