Can we all agree that a pull-up is one of the greatest exercises of all time?
Today alone I had two different people ask me what my bicep routine was, and they seemed dumbfounded when I told them that pull-ups are pretty much all I do. I did a pyramid set of 100 pull-ups today (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1) and I can't remember the last time my biceps and forearms burned so much. Toward the end I was literally hanging by the tips of my fingers, but thankfully my grip strength held up enough for me to complete the routine. And of course I got an excellent back and lat workout as well. No amount of dumbbell curls or lat pull-downs can compare, in my opinion.
So for those of you who are serious about developing rock-hard biceps and forearms (while still adding size, albeit probably smaller than doing tons of curls), then please consider throwing pull-ups into your routine.
