The Armstrong Pull-Up Program is a high-frequency routine attributed to Major Charles Lewis Armstrong. It was designed around improving strict pull-up performance for military fitness testing.
The historical record claims often repeated with the routine are not independently verified here. The useful part is the documented five-day structure and training-set progression.

The push-up work appears in preserved copies but is secondary to the pull-up plan.
Some later copies omit the wide-grip line on Day 3. The nine-set version is the more complete preserved sequence.
A training set is a fixed number of clean reps you can repeat across Day 3 and Day 4. Do not set it from your single best set. Start low enough to maintain the same rep count as fatigue builds.
On Day 4, if you complete at least nine training sets, add one rep to the training set the following week. Otherwise repeat the same number.
Track set-by-set reps on Day 1, the highest completed pyramid rung on Day 2, and the number of training sets on Days 3 and 4. Progress is a trend in total quality work—not a promise that every week produces a new maximum.
Use Day 5 to revisit the day that limited you most. Keep the original rest rules so improvements are comparable.
Remove other high-volume pull-up work while running Armstrong. Keep the rest of your program manageable and avoid adding several hard rowing or curling sessions just because the routine uses bodyweight.
Five consecutive pulling days can irritate elbows or shoulders. Reduce volume, change grip or stop if pain is worsening rather than treating pain as required progress.
Use a few easy scapular pulls, hangs or assisted reps before hard work. A long generic cardio warm-up and several tiring pull-up sets are unnecessary.
Armstrong is a focused pull-up block, not a complete strength program. Use the tracker, keep the training set sustainable and judge it by strict-rep progress without assuming a guaranteed twenty-rep result.
