Best Rep Range for Growth

A common question among trainees is the best rep range to produce muscle growth or hypertrophy.  The best answer is, it all depends. The basic parameter for muscle growth is a rep range between 6-10 reps. That gives us a basic range to work with. What you need to do is to determine if the muscle group you are training is mostly fast twitch or mostly slow twitch fibers. If it is fast twitch,the best rep range is going to be 6-8 or a time under tension of 30-45 seconds. 

A muscle that is mostly slow twitch thrives on a rep range of  12-20 or a time under tension of 90-120 seconds. Many muscle groups are a combination of the two. In that case, a middle ground is best. A good time under tension for this composition is 60-90 seconds. 

Of course, all sets should be taken to at least muscular failure with some HIT variables added in every second workout.  Remember that muscles that are mostly fast twitch will gain the most muscle because that is the fiber type that is most responsible for muscle strength and size.  Slow twitch fibers thrive on aerobic or endurance activities but will increase somewhat in size and strength but not anywhere near what fast twitch fibers will.

In an upcoming post, I will outline a method to determine what type of fiber you have for each muscle group.
