In this video, Rodrigo Barros explains that scientific studies show training a muscle more times per week yields better hypertrophy results. He illustrates the concept using a chest (peitoral) example: training chest twice a week with three exercises per session results in six exercises weekly, and assuming three sets per exercise, that totals 18 sets. He argues that those 18 sets can be redistributed across three, four, five, or six training days—a process he calls “horizontalizing the stimulus.” Because each session’s volume is smaller, recovery is faster; a 24‑hour window is sufficient for the muscle to be ready for another workout. Barros also shares a coaching tip: when a client wants to develop one muscle more than another, you cannot simply repeat the same workout on consecutive days, as that would lead to overtraining. Instead, you must spread the volume across the week to balance development and avoid excessive fatigue.
