Muscle Mass and Power With Negative Overload

Q: My training partner and I are arguing. He wants to start using heavy negative-only training, but I told him that your e-book [the X-centric Mass Workout] warns against it. He reads your newsletter, so please convince him that it’s not a good idea.

A: In the X-centric e-book we cited a study that showed the extreme damage caused by negative-only training (someone lifts the weight for you, and you lower slowly). Muscle recovery for some of the subjects took weeks; however, most of those subjects were untrained, so they didn’t have the cumulative capacity to handle traumatic loads. If you’ve been training for a year or more, that’s probably not your case… [Read more…]

Stretch Overload: Your Mass Gains Will Explode

Q: You’ve mentioned an animal study that produced a 300 percent muscle mass increase after only a month of stretch workouts. That’s truly incredible. Is there more info? How do I duplicate those stretch procedures in my workouts to get that kind of muscle growth?

A: We refer to that animal study by Antonio and Gonyea in many of our X-Rep e-books, but the most extensive analysis was in X-Rep Update #1. Here’s a quote from Jose Antonio, Ph.D., from that e-book: [Read more…]

Explosive Reps: Mass-Building X Factor

Q: I just saw an interview with a top pro bodybuilder, and he said one of the keys to building mass is to explode at the bottom of every rep and attempt to move the positive rep as fast as possible. Are explosive reps a good idea? I’m afraid of getting injured.

A: The big pros are the genetic elite with superhuman muscle-fiber density, as well as ironclad tendons and ligaments. And don’t forget that many use growth hormone, which fortifies cartilage, tendons, and ligaments even more (that’s why many athletes use it—to quickly rehab soft-tissue injuries and prevent others from occurring in the gym and on the field.)

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…]
