Sarcoplasmic Muscle-Size Myth?

Ronnie Coleman in a most muscular pose

I received an email insisting that the sarcoplasm doesn’t make a muscle bigger. Remember, the sarcoplasm is the “energy fluid” in the muscle that contains ATP and other substrates.

That used to be a prevailing belief; however, here’s a quote from hypertrophy researcher Brad Schoenfeld, Ph.D. on the subject: [Read more…]

Misinterpretation of My Size vs. Strength Rant

Steve doing dips

In yesterday’s newsletter, I was NOT saying that if you get stronger you will get bigger. Leverage, learning the movement, and neuromuscular efficiency can account for strength increases.

I knew a skinny guy who worked up to a 350-pound bench, and his pecs and arms sucked. He still looked skinny all over—although he was a little beefier than if he’d never lifted at all… [Read more…]

Stronger to Get Bigger?

Steve in a side most muscular pose

Q: Do you think that it’s essential to increase training weights or at least reps on a given exercise over time to increase muscle growth significantly?

A: I do think you need to get stronger to a degree to get bigger—at least from a fast-twitch-growth standpoint, which is known as myofibrillar hypertrophy…

Something in your workout has to change. If everything stays the same, so will your physique. However… [Read more…]

The Full-Muscle Look

Q: I read that after a back workout, your lats should feel heavier because they’re so filled with blood. I’d never felt that before until I tried the back program in The Ultimate Power-Density Mass Workout. Do you think I got that mega-pump and fullness because the routine alternates power sets with density sets? By the end, my lats were the most pumped they’ve ever been. My delts got insanely big too after the shoulder workout. I even saw veins! I’m psyched that I may finally get in the shape that girls will notice. Thanks.

A: You’ve hit the nail on the head. The bodypart routines in that Power-Density Mass Workout are designed so you stress the myofibrils, the force-generating actin and myosin strands in muscle fibers, with POWER sets, then you follow with DENSITY for sarcoplasmic expansion. The sarcoplasm is the energy fluid in muscle fibers… [Read more…]

Double Your Muscle Growth With X-Factor Firepower

Incline barbell presses

Q: I’ve had phenomenal muscle-size gains and strength increases since switching over to X Reps. I gained five pounds my first month with them! My question is, Do those build more of the myofibril strands or sarcoplasm fluid [in the muscle fibers] that you guys have been talking about? And can I use X Reps on 4X sequences?

A: For the uninitiated, X Reps are eight-inch partials you do in the semi-stretch position at the end of a set to failure. For example, when no more full-range reps are possible on incline presses, you lower the bar to about two inches off your chest and fire up to just below the halfway point for about three to four controled X-Rep explosions… [Read more…]

Get-Big Tip: How to Flip the 4X Growth Switch

Jonathan Lawson doing lat pulldowns

Q: I got The 4X Mass Workout e-book, and it’s fantastic! I tried it on arms for a few weeks, and they blew up at every workout. I measured, and I gained a quarter-inch in only three weeks. Thank you! They’d been stuck for over a year at just under 17″. I’m convinced and ready to use 4X on all bodyparts. I want to do your full-range Positions of Flexion method for each muscle, 4X on all exercises, but the POF routine in the 4X e-book is a 2-way split. I don’t think I can work legs and chest on the same day. Is there an alternative?

A: Don’t be a wuss! That’s the Phase 2 Size Surge program Jonathan used to pack on 20 pounds of muscle in 10 weeks, so suck it up and just do it…

Kidding! That 2-way split is too taxing for some trainees (not just wusses), which is one reason Jonathan provides a 3-way POF split in his Size Surge e-book (pages 55-57). Here’s how that less-taxing mass plan pans out… [Read more…]

Solving the Big-Muscle Puzzle

Jonathan Lawson doing dumbell shrugs

Q: Thank you for clearing up the muscle-growth mystery for me. I always believed in going heavier and heavier to get bigger. Now I know that’s only a small part of the puzzle. Working in the 4X method, X Reps, drop sets, and even some of your high-rep TORQ sets has already gotten me bigger in just a few weeks. My question is, Do you think some people get a better size response from power training and others get more size from density [endurance] work?

A: Absolutely. As we mentioned in a previous newsletter, the BIGGEST powerlifters don’t train for sarcoplasmic (endurance fluid) expansion yet have good muscle size. That’s because they were big dudes in the first place, which may signify more myofibril-building capacity. That would explain their extraordinary strength. The myofibrils are the actin-myosin strands inside the muscle fiber that generate force, but for most trainees that’s not the key to ULTIMATE SIZE… [Read more…]

The Forgotten Size Concept for Ultimate Mass

Mentzer side triceps - Arnold vs. Mentzer—No-Cardio Fat-to-Muscle Training

Q: I’ve read a lot of Mike Mentzer’s high-intensity info, and he said that the pump didn’t matter as far as muscle growth is concerned. He said a lot of the biggest powerlifters never get a pump yet carry a lot of mass. So shouldn’t heavy sets be the core of a mass-building routine?

A: Mentzer was partially right—but leaning more toward being mostly wrong. You don’t need a pump IF you’re only after primarily myofibrillar growth (strength). The myofibrils are the strands of actin and myosin inside the muscle fiber. Those grab onto each other to generate force. Training heavy increases their size and your strength—but science is finding that they are more about producing strength with less-than-stellar effects on muscle size… [Read more…]

Overtrained? Try This for Instant Muscle Gains—No Layoff Necessary

Q: I’m starting to drag at the gym, and I don’t look forward to my workouts anymore. I’m starting to think I’m overtrained. I haven’t grown in a while, but I DON’T want to take a layoff. Even backing off to low-effort workouts sounds like a bad idea because I don’t want to lose my gains. What should I do?

A: Boy, does that sound familiar. We always tell trainees that they need a break to regenerate and keep the growth process rolling, but they never take one (and neither do we—bad). That’s an easy way to end up overtrained. [Read more…]

Fast or Slow to Grow? Here’s 2 Get-Big Tactics

Q: I had your original 10-Week Size Surge book from many years ago and just picked up the Size Surge 2.0 e-book. Thanks for revising it to include 4X training! I’m 45 now with a lot of joint damage from heavy “lifting,” if you want to call it that. So your [moderate-weight] 4X method is perfect and has me making new muscle gains. Thank you! My question concerns the “finisher” set you recommend in one of the workouts. Do you think pure-negative or negative-accentuated sets are better?

A: For the uninitiated, the Size Surge 2.0 e-book has a few new workouts compared to the original, including an alternate Phase 2 routine that’s Positions of Flexion with a few heavy sets, 4X work, AND a one-exercise mass finisher using an intensity method… [Read more…]
