Ultra-Higher-Rep Isolation for New Mass Creation?

Q: I tried Arnold’s method of using a high-rep set to end my major exercises, like bench presses, (Ultimate Power-Density Mass Workout e-book, Chapter 1). But I’m just too fatigued to feel the target muscle on that last set. After reading about Doug Brignole’s 50-40-30-20-10 method in Chapter 4, I was thinking about using that on an isolation exercise to feel the target muscle better, like crossovers for chest after bench. Is that a good idea?

A: It could be, but you left a lot of variables out. For example, how experienced are you? That amount of work may be too much. How many days per week are you training each muscle? If it’s once, that amount of volume may work well, if it’s twice, maybe not.

Best Rep Speed for Muscle Growth

Q: What is the best rep speed for muscle growth? I want to look like a bodybuilder/physique athlete, so I’m not that concerned with strength. I just want more muscle mass.

A: In The X-traordinary X-Rep Workout e-book we cite a study that attempted to determine the optimal rep speed for building muscle. It compared doing sets with a two-to-three-second positive and a two-to-three-second negative—about three up, three down—with sets using a power cadence, which is one second up and three seconds down. The power cadence produced the most mass in this study. [Int J Sports Med. 30(3):200-204; 2009.] [Read more…]

The Power of 10

Q: I’m a bodybuilder and very interested in trying the 10-sets-of-10 method you’ve been writing about. I’m worried because using lighter weights and short rests [between sets] would appear to build primarily the slow-twitch and the fast-twitch endurance fibers [2As], and neglect the power fast-twitch 2Bs. Shouldn’t I be using heavy weights to get at the key 2B fibers?

A: You’re right, the 10×10 method primarily builds the type-2A fibers, those fast-twitchers with an endurance component (that’s why it works so quickly, as you’ll see in a moment). You don’t entirely neglect the 2Bs, however… [Read more…]
