@mekkaokereke as a former physical therapist I can attest that women are qualified and excellent at coaching men in matters of athletic performance. We just don't see it for what it is.
The people who help you relearn how to walk after a stroke, rehab from ACL surgery, return to jogging after back pain, or jump again after an Achilles injury are all coaches at the end of the day... and most of them are women.
It's in a medical setting, but we're 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?
Do we really think that people who can train someone with a spinal cord injury to stand again by helping them recruit 20% more quad muscle can't also train someone to 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.
