Min erfaring er ihvert fald at 12 reps er noget nær det maksimale hvis der skal køres med en vægt der er noget ved og man ikke bare skal slås med mælkesyre.

The mechanisms of muscle hypertrophy - Brad J. Schoenfeld 2010 skrev:PRACTICAL APPLICATIONS
Current research suggests that maximum gains in muscle hypertrophy are achieved by training regimens that produce significant metabolic stress while maintaining a moderate degree of muscle tension. A hypertrophy-oriented program should employ a repetition range of 6–12 reps per set with rest intervals of 60–90 seconds between sets. Exercises should be varied in a multiplanar, multiangled fashion to ensure maximal stimulation of all muscle fibers. Multiple sets should be employed in the context of a split training routine to heighten the anabolic milieu. At least some of the sets should be carried out to the point of concentric muscular failure, perhaps alternating microcycles of sets to failure with those not performed to failure to minimize the potential for overtraining. Concentric repetitions should be performed at fast to moderate speeds (1–3 seconds) while eccentric repetitions should be performed at slightly slower speeds (2–4 seconds). Training should be periodized so that the hypertrophy phase culminates in a brief period of higher volume overreaching followed by a taper to allow for optimal supercompensation of muscle tissue.
