Check her out on Wikipedia, and the following link https://www.rt.com/sport/409845-female-bodybuilder-natalia-kuznetsova/(She says at an Interview rt website):
Nataliya Kuznetsova: I took a break because of the situation in bodybuilding competitions. I was preparing for a competition in the USA, but at the very last moment my visa was declined. But I guess it was for the best, as I didn’t really agree with the result of the contest. And then again, you don’t really earn much from going to competitions, you rather spend money. Now I’m in good shape, it brings me recognition and good business offers. I’d even say that I have more business offers than I used to have going to competitions. You can be a champion, but have no fans. The most important thing is to be in good shape, that way people will always be interested in you.
RT: What about your powerlifting achievements?
NK: At the moment, my personal record in bench press is 175kg (385lbs), 240kg in deadlift and 280kg in squat.
RT: What are your current muscle measurements?
NK: It’s hard to say as they are constantly changing. Most recently I had 48cm (19in) biceps, 74cm hip, 70cm waist, 127cm breast, and I stand 170cm. My weight at the maximum was a little more than 100kg (220lbs).
