Double-X Overload Warmups?

Vascular forearm - 2 Easy Ways for BIG Muscle Gains

Q: I’m making some incredible progress using your Double-X Overload technique, but I wanted to let you know that I don’t just use it on my work sets. DXO works for warmup sets, too. I usually use it on at least one of my two warmup sets for the big [midrange] exercises, and I feel much stronger on my work sets. Great technique!

A: That’s a good tip. We love feedback from fellow weight trainers who think instead of just following the pack. One reason Double-X Overload (DXO) works so well on warmup sets is because of the enhanced occlusion and nervous system activation.

For those unfamiliar with DXO, it’s an X-Rep partial in the semi-stretch position between each full rep. That provides a slightly more explosive action, which has been shown to heighten nerve force (many top-level powerlifters do light, explosive sets for that very reason—it helps them lift more weight).

Should I Do More?

Q: I’ve noticed in a lot of your e-book routines that you often recommend just two work sets for an exercise Why? Should I do more? I’ve read that most bodybuilders do four or five sets per exercise.

A: As Arthur Jones, the creator of Nautilus machines said: “You can train hard or you can train long, but you can’t do both.” Short and hard or long and not so hard both work. Despite what some die-hard high-intensity trainers say, gradually increasing volume is a form of overload that can result in more muscle—if you don’t overdo intensity. It’s a balancing act. Us? Regardless of whether it’s one of our low-set workouts or high tension time workouts, we’re about efficiency of effort in the gym…

The Best Workout Program for Building Muscle

Q: I just want the best workout program for building muscle. Please simplify all the rhetoric and just tell me which one is the absolute best.

A: That’s easy. There is no best routine. It’s the nature of how the human body adapts. We always say it takes change to trigger bigger gains, and some experts suggest that the body is fully adapted after only four workouts.

That’s the reason our own programs are constantly evolving—a new exercise, a new X-hybrid tactic, a drop set, etc. And after 10 weeks or so, we often move to a new program from one of our e-books (Jonathan recently went all the way back to our first X-Rep transformation program, with a few new alterations).

Photos and Freakiness

Q: I saw your before and after photos from your first X-Rep year contrasted with the following year when you gained 10 more pounds of muscle [with X-hybrid techniques]. Personally, I don’t think you look better. You both look bigger, but I think your physiques are more impressive the X-Rep year.

A: Well, that’s not a question, but it’s a relevant opinion—bigger is not necessarily better. In Jonathan’s case, you are seeing his most-muscular pose, and when you gain more muscle, your physique can look more “crowded” in that pose. You could argue that his muscles are starting to look too big for his frame. Steve, on the other hand, is in a semi-relaxed pose in the X-Rep photo, and a twisting ab shot in his Beyond-X photo. He looks considerably bigger in the “after” photo, but it’s a different pose, which makes it difficult to judge.

Triggering Big Size Gains With One Unique Set

Q: I am a fan of your mass tactics like X-Fade, Static X and, of course, X Reps. You often list the ones you use in a workout, but often you list a 4X sequence as (4×10 + StatX). Do you do the [end-of-set] static hold on all sets, some sets or just the last set?

A: We never use those end-of-set mass tactics on more than the last two sets of a 4X sequence. And usually, it is only one unique set… [Read more…]

X-hybrid Techniques: DXO vs. 1 1/4s

Jonathan Lawson concentration curls - X-hybrid Techniques: DXO vs. 1 1/4s

Q: I have your e-book with all the X-hybrid techniques [Beyond X-Rep Muscle Building]. I’m having some excellent workouts integrating one or two every time I train. My question is about Double-X Overload. As you describe it, I do a quarter rep down near the stretch position between each full rep, but I’ve also read you guys say you’ve used 1 1/4s. What’s the difference? Isn’t DXO the same as 1 1/4s?

A: The simple answer is that Double-X Overload (DXO) stresses the STRETCH or semi-stretch point—when the muscle is elongated. For example, at the BOTTOM of a press or flye. [Read more…]

One Key Change for Fast Size Gains

Jonathan Lawson dumbbell incline flyes - One Key Change for Fast Size Gains

Q: I’ve been using the X Fade and Double-X Overload techniques from the Beyond X e-book, and I’ve gained six pounds in one month. My previous workouts were always heavy training, so I’m wondering if maybe I added so much muscle with those methods because they’re giving me some density I’ve been missing. They both make my sets last longer. Could that be it?

A: That’s a distinct possibility, although there’s more to it, as you’ll see. But as you suggest, most wanna-be-big bodybuilders rely almost predominantly on heavier, lower-rep training, and their sets last only 20 seconds or less (time your sets; you will be surprised!). That’s a mistake if you want maximum mass and fast size gains…

A set of 20 seconds or less is power emphasis—but you need BOTH power and density to get TOTAL growth in the majority of the muscle fibers. With those two X-hybrid tactics, X Fade and DXO, you definitely have been X-tending your sets—more so with DXO, which we really like on stretch-position exercises like flyes…

Jonathan Lawson dumbbell incline flyes - One Key Change for Fast Size Gains

DXO: This is simply adding an X-Rep partial near the stretch position between EVERY full rep—so each of your reps is really a 1 1/4 rep. The “hitch” at the bottom between each full rep emphasizes stretch overload, which has been shown to induce everything from hyperplasia, or fiber splitting, to anabolic hormone release in muscle tissue. Plus, as you noticed, it puts more of a mass-building density spin on the set as well…

If you do 9 reps in DXO style, your set will last more than 30 seconds. Now you’re getting into density territory for adding size to that side of the key type 2A mass fibers. That’s a great get-bigger trigger, especially if you’ve been using mostly power sets. Your six-pound muscle gain in one month is no doubt due to a combination of density and heightened fiber activation. You get both of those with DXO—and the X-Fade technique…

X Fade: With this X-hybrid tactic you do a standard set of, say, cable flyes, a contracted-position exercise in the Positions-of-Flexion mass-building protocol. When you hit full-range exhaustion, where most bodybuilders end the set, you get the cable handles back up to the contracted position—a partner can help—and do three to five short partials there, flexing the target muscle…

Then you lower to the stretch position and do standard X-Rep partials there. If you can’t manage any movement at either position, just hold for a static pec contraction for a few seconds at each spot—top flexed and bottom stretched. Key growth fibers will still be firing and you should wake up some dormant ones as well for new size stimulation—you’ll feel it…

Doing end-of-set X-Rep partials at BOTH the top and bottom of the stroke with the X Fade will add maybe six to eight seconds to your tension time. Nevertheless, both DXO and the X-Fade tactic are excellent ways to get more density training, activate more growth fibers to fire and give you excellent change to fuel fast size gains.

ATTENTION OVER-40 BODYBUILDERS

One of the most interesting read-me pages on Testosterone and other muscle-building hormones we’ve seen is The Truth About Testosterone.

It even talks about a fruit, a specific part, that can up your T naturally. Cranking up your testosterone will not only get you jacked in the gym, but in the bedroom too—not to mention help rip up your midsection as it ignites fat burning. If that interests you, there’s more from our colleague and registered dietician, HERE.

Use DXO to Grow

Jonathan Lawson dumbbell flyes - Use DXO to Grow

Q: Positions of Flexion is working great for me, but I’m having a problem with chest, specifically flyes. I know how important the stretch position is. You guys talk about the animal study that produced the huge [300 percent] muscle gain in one month with only stretch overload. That’s why I’m using the more focused 3-way POF pec routine in Chapter 5 [of the 3D Muscle Building e-book]. I do bench presses as my first [midrange] exercise, then flyes for stretch, and cable flyes for the contracted position. I just don’t feel the flyes at all, so I know I’m missing important mass stimulation. Any suggestions?

A: For those of us with below-average nerve force in our pectoral muscles—that includes both of us—dumbbell flyes can be difficult to feel. Well, that’s not completely true; they sometimes “feel” like a waste of time. That’s because the front delts and arms tend to take over and get the brunt of the size-building stress. [Read more…]
