Intensity versus volume
Why this programme starts with fewer, more purposeful sets.
The short answer
More hard sets can add growth, but each additional set tends to provide less benefit while still costing time and recovery; this plan starts with the smallest useful dose.
The balanced position
Higher-volume programmes can work very well, especially for people who enjoy longer sessions and want to pursue the maximum possible growth. The relationship is not linear: ten sets are not automatically twice as productive as five.
The first challenging sets usually offer an excellent benefit-to-cost ratio. Later sets can add stimulus, but they also add fatigue, soreness and time. A busy beginner benefits from capturing the high-return part first.
Hard sets are useful, not magical
The repetitions near the end of a demanding set often require the greatest recruitment and effort. Earlier repetitions are not wasted; they create the fatigue that makes the later ones difficult. Nobody can count 'effective repetitions' with perfect precision.
Remember: Begin with little, execute it well and add volume only when the logbook gives a real reason.
