Get More Fat Burning

Jonathan Lawson outside in the sun - Get More Fat Burning

Q: I just started the 4X Mass Workout, and I really like it. I feel bigger already. I still have some fat to lose, so I also got your Ultimate Fat-to-Muscle Workout. Can I incorporate the negative-accentuated sets from that into a total-4X program somehow to get more fat burning?

A: NA sets are one second up for the positive and lowering in six seconds for the negative. That slow, negative-accentuated style triggers more muscle damage, which requires more energy after the workout for repair. And that energy requirement means your metabolism is amped to help you get more fat burning. [Read more…]

The 4X Get-Bigger Trigger

Jonathan Lawson cable curls - The 4X Get-Bigger Trigger

Q: I gave the 4X method a try, and it feels amazing. Definitely a big pump. I’m just worried that since only the fourth set is to all-out failure that I’m not getting enough intensity to stimulate growth. I’m used to doing two to four sets on each exercise to total exhaustion. Will my muscles regress on 4X?

A: In The 4X Mass Workout e-book we explain the all-or-none principle of fiber activation. What that means is that a muscle fiber fires at 100 percent or not at all. So even on SUBFAILURE sets, you’re getting bundles of fast-twitch fibers to fire completely. [Read more…]

Pumped to the Max: Look Big All Day Long

Jonathan Lawson in gym/shadows - Pumped to the Max: Look Big All Day Long

Q: The 4X Mass Workout is awesome! I feel and look big and totally pumped all the time, and I love it. I know I’m getting bigger from every workout, but will I get stronger too [using the 4X method]?

A: The 4X Mass Workout is designed to get your muscles as big as possible as quickly as possible. It’s why a number of pro bodybuilders use it or something similar the last weeks before a contest (there’s more on that in the e-book). You will gain some strength, but that’s not the PRIMARY objective of 4X training…

The 4X mass method is a supersaturation size-building program. Use it for four to six weeks as we suggest in the workout and we guarantee you will look big and GROW.

For those not familiar with 4X, you pick a weight with which you can crank out 15 reps, but you only do 10. Rest 30 seconds, then do 10 more, and so on until you complete four sets of 10 reps in less than FIVE MINUTES…

As we mention in the 4X Mass Workout e-book, you get a BALANCE of power and density on the first exercise, but the fatigue is fierce as you move through a bodypart workout. It rapidly turns to a major density hit for the key 2A growth fibers [the 4X e-book explains that, but you may have skipped right to the programs, which is what a lot of trainees do—they can’t wait to hit the gym with the workout.]

If you’re worried about using medium poundages instead of heavy weights, there are a few ways to incorporate power-building sets into the 4X Mass Workout. See the Q&A chapter in that e-book. One way is to do the first BIG exercise as a power pyramid instead of in 4X style.

With or without those pure power sets, 4X will give you a blast of new mass fast!

Till next time, train hard—and smart—for BIG results.

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.

Are You Working Out Too Hard?

Steve spotting Jonathan for forced reps

Q: I train my butt off in the gym. I hit it harder than every other guy in there, but I haven’t gained much muscle in a long time. Is it my genetics? My nutrition is perfect, so I should be growing like crazy, but I’m not. It’s very frustrating… Help?!

A: Yes, your genetics could have something to do with it; HOWEVER, you may have just been working out too hard for too long. It’s time to step back with a new plan… [Read more…]

Do This, Not That, to Grow Muscle Fast

Jonathan Lawson Smith machine incline presses - Do This, Not That, to Grow Muscle Fast

Q: I have almost all of your e-books, and I’ve learned more from them than I have from anywhere else in the 10 years I’ve been training. Thank you. I just got The 4X Mass Workout and had a question: You always say “change to gain,” but you tend to use the same few exercises in a lot of your programs. Shouldn’t I switch moves often to gain mass, like use dumbbells instead of a barbell?

A: While variation is important, you need to focus on the exercises that you feel the most. That’s especially true for weak bodyparts, which tend to lag due to inadequate neuromuscular efficiency, or nerve-to-muscle connections. A good example for us, and most bodybuilders, is upper chest exercises. [Read more…]

Muscle-Building Myth Exploded: Power vs. Density

Big arm measurement - Muscle-Building Myth Exploded: Power vs. Density

Q: I have two of your e-books, The Ultimate Power-Density Mass Workout and the X-centric Mass Workout. They’re both great, and I’m already seeing results applying the methods. My question is, you say that you need both power sets and density sets to get extreme muscle gains quickly, but which is more important? Should I do more of one than the other for fastest muscle gains?

A: If you would’ve asked us that several years ago, we would’ve said power, no question—because, like most bodybuilders, we had been brainwashed into believing that heavy weights and fairly low reps are the keys to maximum mass fast. But according to our recent experiments as well as many done almost 50 years ago, that’s not the case for most, so it’s a big-time muscle-building myth… [Read more…]

Quick Muscle-Mass Tip: Density-Expansion

Jonathan Lawson cable curls - Quick Muscle-Mass Tip: Density Expansion

Q: On the X-centric Mass Workout, I’m getting a lot bigger and stronger using the 4×10 finisher for all body parts. It’s great! My question is, as I get stronger should I stop at 10 on the last set, even if it’s easy? Or should I keep repping until muscle failure [on the fourth set]? I know to go up in weight at the next workout, but I don’t want to waste the one where the weight is easier.

A: For the uninitiated, 4×10 (from the 4X Mass Workout e-book) is taking a weight that you can get about 15 reps with, but you only do 10. Rest 30 seconds, then do 10 more and so on until you complete four sets. If the weight is right, you shouldn’t get 10 on your last set or two. If you do get 10 on your last set, add weight at your next workout… [Read more…]
