In this segment, the presenter argues that training a muscle two or more times per week leads to greater hypertrophy than training it once, provided the total weekly volume and number of sets remain equal. He emphasizes that this claim is grounded in scientific studies conducted with natural (non‑hormonized) lifters, noting that the overwhelming majority of research on training variables—such as volume, weekly stimulus, exercise selection, and range of motion—focuses on natural athletes. He points out that studies involving hormonized individuals are scarce and typically examine the direct effects of the substances themselves rather than training protocols. The speaker’s purpose is to correct the misconception that higher frequency is only relevant for hormonized athletes and to underline that the evidence supporting increased frequency applies to natural lifters.
