Erin Oprea, a Nashville personal trainer, banned for five years by USADA for using banned substances. The ban follows a positive test for experimental muscle-building drugs and synthetic testosterone.

Oprea, who trained celebrities like Carrie Underwood, was provisionally suspended since June 16. The five-year ban starts from that date, disqualifying her from sanctioned races until June 2031. Read more culture coverage.

The lab detected ostarine, LGD-4033, and synthetic testosterone in her sample. Both ostarine and LGD-4033 are SARMs, not approved for human use, and are banned in and out of competition. Related: Clayton Young Aims for American Marathon Record in Chicago.
