re: Could you beat a 135 pound female mma fighter (amanda nunez)without training?

I agree, powerlifters max bench presses often move the bar a few inches, if that.
And I acknowledge none of that has anything to do with the initial post. Just noting for the poster that his stats are wrong, there are women who are stronger than him at a lower bodyweight.

Back to topic, any man of almost any size with any significant combo of fight/combat sport training and strength training, would defeat Nunez almost every time. The poster complimenting his bench press probably isn't in that category.
