I recall reading somewhere she was a practitioner of martial arts before getting into bodybuilding.
I believe you are correct my friend. she is indeed a martial artist. There are at least two articles mention it.
The first article here states she's an expert in Karate. The second article is in french and the last time I used French was in the 70s. From what I can gather, I think it's written that she's a 2nd degree black belt in Karate, but may had to stop due to a leg injury.
If there is some kind French speaking member, they may be able to confirm it.
