Pullup Volume

You start with an all-out set and then cut a rep in each consecutive set for a total of five sets.
The next day add a rep to the last set. Then a rep to the set before that, etc. The system is
intended to be used for four weeks. In the end of the month take two or three days off and
then test yourself. It is not unusual to up the reps 2.5-3 times. In other words, you are likely
to end up cranking out 12-15 reps if you started with 5. If you can already do between 6 and
12 reps start the program with the first day your PR shows up. For instance, if your max is 6
pullups start with Day 7; if your max is 8 start with Day 19. If you run into a snag with this routine, back off a week and build up again. If you hit the wall again switch to another routine.
