I had 2 judo green belts. A man and a woman. Both same weight, close to same height etc. The woman would out technique the guy like nobodies business. However, if and when she lost it is because she got out muscled.
However when she competed against other women she destroyed them. I have always enjoyed training with women in class settings. Like I said before "If a woman can figure out how to win competitively then I want to learn how she did it."
Happened to me all the time except I was outweighed all the time. At some point technique won't save you, strength and power matter. The better the technique the the more you nullify the brute strength difference.
