More Muscle Size: One-Set Wonders

Q: I just got your X-traordinary Arms e-book. Killer information, and I’m ready to use it to build mine into 19-inchers like Jonathan’s. My question is about the 3D HIT program in which you incorporate the arm-specialization routines. One work set for each exercise? You list a few more sets for arms, but I just can’t comprehend how one set could be enough for the other bodyparts. Can I add sets?

A: You can do anything you want, but be careful and monitor your progress. Building muscular size is all about experimentation. In fact, the 3D HIT program is our experiment into one-set-per-exercise intensity training. We’ve seen lots of research validating one-set training for building strength; however, as we explain in our e-books, packing on extreme muscle size is a different animal than merely building strength and a few fast-twitch fibers. There are different layers to attack when size is the goal. [Read more…]

Moment of Bodybuilding Zen 44: Jim Haislop’s Proportion

Look Like a Bodybuilder

Jonathan Lawson's back, before and after

Q: I’m a powerlifter, but I want a better physique. I’m not sure how. I’ve got some muscle, but I sure don’t look like a bodybuilder. What should I do? I’m thinking I just need more isolated exercises for each muscle, like pushdowns for triceps. If I keep pushing heavy weights on all those exercises, I’ll look more like a bodybuilder, right? Do any of your e-books address my problem?

A: You gave a clue to one of the big reasons so many trainees make slow-to-no muscle gains: They’re brainwashed into believing that heavy training exclusively is what builds mass. That’s simply not true… [Read more…]

Moment of Bodybuilding Zen 19: Danny Padilla

Danny Padilla was known for his classic, no-flaws physique. His nickname was “the Giant Killer” because at only 5’2” his perfect mass-symmetry combo allowed him to beat bodybuilders who were much taller and larger than he was. [Read more…]

#1 Mass-Building Discovery—Surprising Find

Jonathan Lawson doing chin-ups

Q: You guys have contributed so much to my ability to build lots of muscle. I want to thank you. X Reps are fantastic. Positions of Flexion is great; I build most of my workouts around that full-range principle. You’ve also created 4X and negative-accentuated [X-centric] training. So what do you think is the best of the bunch, your #1 mass-building discovery over the years?

A: Out of all of our mass-building tactics, X Reps are probably the easiest to apply. Well, maybe “easiest” is the wrong word because when you use them correctly, X-Rep partials at the end of a set are brutal—they hurt, but they work. X Reps make any set three to five times more effective at packing on mass… [Read more…]

Ultimate Exercise for Shoulder Size

Q: Maybe I missed it since I’m a relatively new subscriber to your newsletter, but what is the Ultimate Exercise for shoulder size; wide-grip dumbbell upright rows or dumbbell presses?

A: We first identified each Ultimate Exercise for every major bodypart in our first e-book, The Ultimate Mass Workout. There’s a comprehensive chapter on each one, why they are best, and also a few complete programs with just those moves—like V-handle chins for lats… [Read more…]

Simplify for Size: Back to Basics to Add Slabs of Muscle

Steve spotting Jonathan for forced reps

Q: In one of your recent newsletters I noticed that you guys recommended using The Basic X-traordinary X-Rep Workout to an advanced trainee. Can someone who’s been training a while really make new gains with such an abbreviated basic program?

A: Absolutely! And the gains can be outstanding, especially after an extreme peaking cycle. When you’ve been training toward a peak day, like a competition, photoshoot, or any other specific goal, you bring yourself to the brink of overtraining—but that’s a good thing, and incredible things happen when you simplify for size… [Read more…]

Exciting Muscle-Size Insights

Lawson incline press Holman spot

Q: After reading one of your articles that discussed the study where light, longer sets built muscle, I was thinking that maybe that’s why X Reps build so much size. Because they’re partial reps where the muscle is stretched, you block blood flow and get more tension time by making the set last longer. Do you think that’s the case—that X Reps work because they make a set last longer?

A: No doubt that ex-tending the set with X-Reps is one reason those power partials are so effective at building more muscle. As you said, you not only pulse at the target-muscle’s strongest point, where it’s elongated, but you also force the muscle to continue firing for five or more extra seconds—which means a longer tension time on any set with X Reps tacked on. That was the ground-breaking finding of that study—that extending tension time was another way to trigger hypertrophic stimulation…

Convert New Muscle Strength to Serious Muscle Size

3D Triceps Positions

Q: I’ve been using the Power Pyramid Program (Chapter 2 in the Freak-Physique Stretch-Overload Workout e-book) for six weeks. I’m getting incredibly strong, but I’ve only gained about four pounds of muscle. I realize it’s a muscle strength workout with a size side effect, but now I’m ready to use my new strength to go for major muscle mass. I also want to get leaner. I’m 5’10” and weigh 200 pounds with 14 percent bodyfat. What type of routine should I follow? I really like using Positions of Flexion in the Power Pyramid Program. Can I just alter that routine somehow for my new goals? 

A: Ah, so now that you’re strong like an ox, you want to get even bigger with some leanness to boot. Sounds good, and it can and will happen. You just need to take your new power in a slightly different direction—still using the multi-angular attack of POF, but altered so you pack on the most muscle size—complete development from origin to insertion.
