Stealth Progression = Muscle Mass Expansion

Jonathan doing one-arm cable pushdowns

I’ve been lifting for a few years now, so adding weight to my exercises is rare. I know that “progressive resistance” is important for muscle size, so do I just put up with slow progress, force it or what?

Bodybuilding is called “progressive-resistance” training because adding weight and/or reps to your exercises can increase muscle size. Consider it a stealth progression… [Read more…]

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

We discuss a lot of mass-building studies, and we often get questions about altering the procedure of those studies to make the mass effect even more effective. What the heck are we talking about? For example… [Read more…]

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?

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…

Best Muscle-Growth Method for You

Goodin bench press

Q: I just started using the 4X methods. Great stuff. Loving the pumps, but I’m wondering if 4X is better for maximum muscle size or Downward-Progression 4X [adding weight each set so reps fall—12,10,8,6] – what’s the best muscle-growth method for me?

A: Both methods provide a powerful hypertrophic Density effect. That’s because you rest only 35 to 45 seconds between sets. That gets you to the critical growth threshold quickly… [Read more…]

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…]

Muscle-Building Mistake You Can’t Afford to Make

Dumbbell flyes, stretch position - Muscle-Building Mistake You Can't Afford to Make

Q: A lot of bodybuilders go all power in the off-season. They push for more strength so size will follow. I’m thinking about using the Phase 1 program in Size Surge for that purpose—mostly big exercises with heavy weights training three days a week so I get plenty of recover-and-grow time. Would that program be okay to use for the entire 10 weeks instead of moving to Phase 2?

A: You’re right, even Arnold used to do a two-to-three-month power phase in the winter—but it wasn’t heavy low reps on every exercise, as we’ll explain. That’s the problem with the way most trainees do it: They go heavy on ALL exercises all the time for too long and neglect critical sarcoplasmic size, which can be a big muscle-building mistake… [Read more…]

Too Much Muscle Too Fast

Thick chest, arms, and shoulders - Too Much Muscle Too Fast

Q: I’m a competitive powerlifter, so I haven’t tried your 4X method. It requires moderate weights, and that’s not me. I need to train heavy. But I have been using your X-centric sets, usually only one or two at the end of each heavy compound exercise, like bench presses and squats. My problem is that I’ve been using X-centric sets for a month, but I’m five pounds heavier. I’m worried because I don’t want to jump a weight class at my next lifting meet. I’m pretty sure it’s all muscle because I’m seeing more striations in my chest, legs, and even shoulders, and many of my bodyparts look rounder. Should I stop using X-centrics? Is this happening because of the extra fiber trauma I’m getting from those sets?

A: The extra fiber trauma from emphasizing the negative stroke on your negative-accentuated (NA) sets is no doubt part of the reason you’ve added new muscle quickly—that causes fiber remodeling, or growth; X-centric sets also cause more fiber inflammation, which can make you look bigger and rounder. But there’s more to it than that (exciting stuff for those of us who want to pack on maximum muscle size)… [Read more…]

Shock-centric Mass Blast

Big arm measurement - Shock-centric Mass Blast

Q: I’ve been using your 4X method and throwing in some NA (negative-accentuated) sets every so often, mainly because I like some soreness. It makes me feel like I’ve done good work in the gym and am growing. Lately, I can’t seem to get much soreness from my workouts. Should I add sets or more NA or what?

A: There is no scientific research that shows that muscle soreness equals muscle growth—but we know what you mean. It makes you feel like you’ve hit the muscle hard enough to trigger growth, and it just makes sense that the microtrauma should translate into hypertrophy. We know for a fact that emphasizing the negative stroke of every rep can cause more soreness and that it can cause inflammation—which is temporary size. But that should lead to permanent mass… [Read more…]

Quick Hits for Muscle Size

Muscular delt and arm - Quick Hits for Muscle Size

Q: I just started the Size Surge Phase 1 workouts, and I like what I’m feeling so far. One concern is that I desperately need more muscle size in my shoulders, so I’m wondering if I can add some lateral raises to the Monday and Friday workouts.

A: The Size Surge Phase 1 program is three days a week, and the Monday and Friday workouts are already loaded with big exercises. We have a better idea for some delt specialization than adding to those two sessions. First, here’s the Phase 1 split: [Read more…]
