  1. The question

    How many sets per week do you actually need to grow?

  2. How it works

    Every hard set signals your muscle to grow. A hard set ends two or three reps short of failure. You don't need to go all the way. Stack up more hard sets, and that signal gets stronger. But your first few sets each week count the most. After that, each one you add does a little less.

  3. The research

    Across sixty-seven studies, more weekly sets meant more muscle. Even four sets a week was enough to make a muscle measurably bigger.

  4. The protocol

    Here's the plan. Each week, aim for ten to twenty hard sets per muscle. With fewer than ten, people still grew, but clearly less. Past about twenty, extra sets brought smaller gains.

  5. The verdict

    So a few hard sets a week start the growth, and more keep paying off. Track your workouts with Anvilus.

§ 03 · In the sources' words

“indicating that gains in muscle size and strength increase as volume increases. However, both best fit models suggest diminishing returns”

“A series of multi-level meta-regressions were performed for muscle hypertrophy and strength, utilizing 67 total studies of 2,058 participants”

“Minimum Effective Dose 4 Sufficient to elicit detectable hypertrophy”

“Lower Efficiency 19 - 29 ~10.75 additional weekly sets required for additional detectable hypertrophy”

“Mechanistic data indicates greater-post exercise MPS and intracellular anabolic signaling for higher volume protocols in humans”

“Sufficient effort (assessed using various scales) can be accomplished by completing sets with various RTx and completion of “near-failure” or a target of 2–3 repetitions in reserve (RIR)”
