See the technical phrasing
When total weekly training volume is held constant, performing resistance training twice per week leads to greater muscle hypertrophy compared to performing it once per week.
When you lift the same total amount of weight, whether you do it once a week or twice a week, your muscles make new proteins at about the same rate. More frequent sessions don’t trick your muscles into making more protein or growing bigger.
