Is more training volume always better for muscle growth?

More volume can produce more growth, but “always” goes beyond the evidence. A controlled study in trained men found greater increases in some muscle-size measurements with higher set volumes over eight weeks. Strength gains did not show the same clear volume advantage, illustrating that different goals may respond differently.[1]

The study compared specific programs in a small group, not every possible number of weekly sets. It cannot establish that adding sets indefinitely keeps improving results. Hard sets, exercise overlap, proximity to failure, and consistency of technique influence what a reported set count actually represents.[1]

Treat volume as something to adjust against results and recovery. If additional sets reduce the quality of later sessions, aggravate pain, or make the program unsustainable, the written total may be rising without a useful increase in training stimulus. Progression and repeatable performance are more informative than copying the largest workload a professional bodybuilder reports.[1]
