High amount of reps increases strength and increases muscle density over time, so someone that does lots of reps to gain strength can be stronger than someone with bigger arms than them.
I did lots of reps for a long time Sets of 25 reps, then sets of 50 reps, and kept working my way up until I could do a set of 100 reps straight with a weight, then I increased it by 50 pounds and went back to 25 reps per set with that.
I ended up a lot stronger than my friends that did few reps but with more weight. And the people doing less reps per set, but closer to their weight limit ended up stiff and slow (muscle bound) even though they weren't as strong.
