What sets and reps work best for building muscle?

About 10 to 20 hard sets per muscle each week can build muscle, with roughly 6 to 30 reps per set when sets feel hard near the end. Technogym’s article outlines Hypertrophy Focused Training, or lifting mainly to grow muscle. It summarizes evidence rather than reporting one new study. Its weekly set range applies to most people who already train. Beginners can grow well toward the lower end. The supplied text gives no study sizes or measured gains in muscle size. The main takeaway is flexibility in reps, with effort and weekly sets counting most. The article describes 6 to 12 reps as efficient for most exercises. This range balances heavier loads with enough repeated work. But muscle growth is not limited to that range. Sets of up to roughly 30 reps can also work when they end close to the point where another rep is impossible. The article puts that effort at about 1 to 3 reps left. In plain terms, you finish while you could still do a few more. Its weekly target counts challenging sets for each muscle group. It is not a total for every exercise combined. For BioSocial members, this offers a useful way to compare training logs. A log could include weekly sets per muscle, reps, and estimated reps left. Members tracking Segmental Muscle Mass can compare those readings with their training records over time. Those personal patterns are useful discussion points, not proof that one rep range caused growth. Sharing training experience also helps put different routines in context. What weekly set counts and rep ranges have you used, and what changes have you tracked?
