Pull ups in beginner program stage 2

Why pull ups only at first day of first week and no more next? What sense to do it only once?

Also wondering this.  It's the same for incline bench press on the first week of #37 in the 3 days sportsmen program.

While there are only three competition lifts there are many others that are not. So just from that fact alone, in a well-balanced program you should expect to squat, bench and deadlift a lot while doing other assorted exercises less frequently.
