Welterweight, or 170lbs, is the hypothetical cut-off between large men and average-or-below sized individuals. At this level, technique cardio and athleticism become paramount factors, over strength and knockout power. Not to say that these don’t also help – just ask the two-time champion Matt Hughes, who was known for his freakish ‘farmer’ strength. Or the current champion Kamaru Usman, whose punching power can be envied by fighters in any weight class.
