@mekkaokereke as a former physical therapist I can attest. In that life, I was surrounded by women who were indeed coaching men in matters of physical performance. People just didn't think of it that way.
The people who help you relearn how to walk after a stroke, rehab from ACL surgery, return to jogging after back pain, or recover from an Achilles tendon strain... they're all coaches at the end of the day and most of them are women.
It was in a medical setting, but we were applying principles of athletic performance to the daily lives of ordinary people who may or may not have needed that coaching for athletic gain.
Oh, but they're at vastly different levels... uh, we really think that people who can train someone with a spinal cord injury to boost quad muscle recruitment by 20% so they can stand, can't also help someone run faster?
Women have been doing this all along. We just discount what they do because we're not used to seeing them in the role of advisors.
