Miss Mary & furfan,
Your comments reminded me that a longtime Mistress of mine, who I found on the old wb270.com female bodybuilder/wrestler site in the '00s, was among other things a fitness trainer. She was also a yoga teacher, professional dancer (not stripper - showgirl/Broadway type) and fitness trainer. She lived cross country, so I saw her once or twice a year. In our second to last session before she retired from the scene we went to lunch and she then took me to her soon-to-be-opened training studio. Of course she could read all over my face I wanted to session, which wasn't planned. The Mistress, in street clothes, immediately turned into her alter ego and ordered me on the floor. I was to do 20 push ups. She sat on a chair with her high heels inches away from my face. I then had to do a few sit ups. I hadn't done those exercises in a while and she knew it. After I finished my workout, she laughed. I was allowed to worship the Mistress' feet and legs. Mistress did give me a nice compliment, saying I had a good physique, but I should work on it with regular training.
The one thing I realized about that particular woman, was that her fetish was control - physical and mental. Yes, she did do non-competitive wrestling, scissors and lift and carry. It was only to show her power over you... and control. That was evident in session and the videos she posts to promote her business today.
