Yes, it was Fred Hardinge.
I just watched that episode on YT. It is available on Doug Bachelors channel. It was full of scripture and testimonies.
She was promoting a basic health message. Fresh water, exercise (Cold Plunge, HIT), nutrition (gut flora).
She is popular because she walks the talk. She is out doing the heavy exercise every day. This commands respect.
She has 6 of her own children.
