I don’t understand how it is that someone with only seven pull-ups could ask me how they could increase their muscle mass or strength. The obvious answer is, “work until you’ve got thirty pull-ups and you’ll come back with 5 new pounds of lats and biceps alone.” This kind of thing is true of squats, deadlifts, push press, muscle-ups, dips and any other fundamental, functional movements. Athletes regularly working the basic movements never ask how they get stronger or bigger they already know.”
