> The meticulous PT format and exercise selection allows them to achieve more muscle gain in 20 minutes per week than median trainees achieve in 2-3 hours.

This is a strong statement that is presented without evidence, and which conflicts with scientific consensus.

Studies show again and again that the most important factors are consistency and training volume.

If the program is more effective, which is questionable in itself, then the reasons are likely 1. reduction of burnout and/or 2. much more intense training. Not PT format or exercise selection.
