Max-Muscle-Size Study: Rest Between Sets—is short or long best?

Q: Your 4X mass method has 35 to 45 seconds rest between sets. I’ve seen research that longer rests between sets can be better for strength and muscle growth. What’s your take on that?

A: Legendary trainer Vince Gironda, the Iron Guru who trained Mr. Olympias as well as Hollywood stars to build muscle fast, first got us into reducing rest between sets for muscle growth—he called it Density Training…

Muscle-Building Myths—Or Are They? (controversial muscle-building info)

Dumbbell flyes showing thick pecs - Mass-Building Myths—Or Are They? (controversial muscle-building info)

Q: I heard that close-grip bench presses can build the inner pecs. But then a pro bodybuilder said that’s false. He said no exercise can build the “inner” pecs—or “lower” biceps for that matter, and that those are muscle-building myths. Which is correct?

A: While close-grip bench presses won’t direct development to the inner-chest area, some researchers suggest that putting a muscle into elongation, or stretch, against resistance can thicken the fibers at the insertion point. For example, doing flyes for more chest beef near the sternum… [Read more…]

Ultimate Exercises for Mass

Q: I’m reading your original X-Rep e-book [The Ultimate Mass Workout], and you have the Ultimate Exercises listed for each muscle. For lats, it’s close-, parallel-grip chins. I have a hard time with chins because I weigh around 220 pounds. Can I do them on the pulldown machine instead?

A: Yes, do them on the pulldown machine for now; however, once you’re strong enough, do the chinup-bar version… [Read more…]

New Size With Full-Body One-Hit Mass Workouts

Torso with muscle fibers (illustration) - New Size With Full-Body One-Hit Mass Workouts

Q: I’ve been reading about the 4X training and am wondering if you have any advice on how to use it with a full-body three-days-per-week routine. I just started using the 4X method for each bodypart.  I do one exercise per muscle.  Monday I do chest, shoulders, back, bi’s, tri’s, abs, legs.  Wednesday I do the same body parts but in a different order and using different exercises. The same goes for Friday. I take the weekend off.  I’m drug-free, so I think I’ve been overtraining till now. I’m hoping that 4X will help spark some new gains.

A: That sounds like a great plan for building more mass. First, skeptical readers need to realize that three-days-per-week programs can do incredible things. We discuss the Colorado Experiment in Size Surge 2.0 and 3D Muscle Building, a four-week research project in which Casey Viator gained 60 pounds of muscle… [Read more…]

Anabolic Drive and 10X Muscle Mass

Jonathan Lawson squatting - Anabolic Drive and 10X Muscle Mass

Q: The 10×10 method sounds great in a number of ways for building muscle size, but one concern I have is the lack of anabolic hormone stimulation. Aren’t heavy, low-rep sets best for that? Should I combine 10×10 with heavier workouts to get that essential anabolic environment for best gains?

A: While doing a number of heavy-weight, low-rep sets can contribute to anabolic drive and hormone release, it may not be the best or most-efficient route. According to a report from Jerry Brainum, three groups were compared, and all subject performed the squat: [Read more…]

STX + SEX for Massive Muscle Growth

JL Arm Muscle Fibers - STX + SEX for Massive Muscle Growth

Q: The Anabolic Reload Mass Workout, with a high-rep set first to fatigue slow-twitch fibers (STX), has helped me add six pounds of muscle in four weeks. Now I’m ready to go back to a three-way split, but the STX method worked so well that I want to keep using it, but after my heavy work. I’m in my 20s, so heavy weights is not a problem. Any suggestions? (Title: STX + SEX for Massive Muscle Growth)

Amplify the Mass Effect? New Look at Key Muscle-Size Study

Extreme Muscle Size: Forgotten Hypertrophy Method

Q: At your suggestion, I’ve been including higher-rep sets in many of my workouts. I’m seeing much more size and vascularity. My question is, do sets of around 20 reps work because I’m getting growth in more slow-twitch fibers or are the fast-twitch ones getting larger as well?

A: Yes, both—and as bodybuilders, we want to maximize ALL hypertrophic pathways, even size in the slow-twitch fibers. Higher-rep sets also give you anabolic hormone surges…

According to Brad Schoenfeld, Ph.D., who conducts studies on muscle hypertrophy,

The Truth About Getting Stronger to Grow Bigger?

Jonathan squatting, dark room

We get the stronger = bigger question a lot—and there’s no question that getting stronger will build some size—note that we said “some.” To clarify, here’s an excerpt from our best-selling e-book The Super-Size Crash Course…

“One of the biggest reasons muscle growth is so slow in most cases is the simplistic myth that strength equals superior size. There’s more to it than that. Trying to move big weights for a few reps does very little for ultimate muscle size. Are you shaking your head? Check this out…

Guaranteed Rise in Your Muscle Size: New Phase 3 for Shocking Hypertrophy

https://www.x-rep.com/downloads/the-ultimate-super-size-crash-course/

Q: The program you outline in the Super-Size Crash Course that put 18 pounds of muscle size on Jordon [Williamson] had him use some heavy pyramid training in Phase 1, but only moderately heavy Downward-Progression 4X in Phase 2. To keep gaining, would you have someone cycle back to Phase 1 for more heavy pyramid training?

A: First we’d probably ask what you’re motivated to do. That’s because nothing breeds more muscle size like the fire to train… [Read more…]
