“Wow! You’re looking seriously bigger, bro.”

Q: I just want to thank you for another killer variation of 4X, “downward-progression.” I’ve only been using it for a couple of weeks on the big exercises, but a guy at the gym came up to me today and said, “You’re looking seriously bigger, bro.” It’s working great and is perfect with regular 4X and TORQ (tension-overload repetition quantity). I’m using DP 4X on the heavy power exercises in The Ultimate Power-Density Mass Workout 2.0, with 4X and TORQ on the others. I’m very impressed, and apparently growing more impressive. Lol. Thank you.

A: Interesting you say that because both of us received similar compliments in the gym when we started rotating in downward-progression 4X. One guy told Jonathan his arms were looking huge, and Steve got, “If you’re trying to get bigger, it’s working.” They both left off the “bro.” [Read more…]

One-Day Blast for More Mass

Q: I’m not gonna lie… I sometimes get bored with my training or just have random days when my motivation is a bit low. That makes it tough to get to the gym, but I really don’t want to skip a day because of that. What if I took random days here and there to do only one exercise for each muscle. Would that be good for growth, and how often could I do that?

A: Any deviation from the norm will shock new muscle size, especially if it’s something that challenges your growth threshold like 10×10 of only one exercise. [Read more…]

Power-Pump: Combo to Grow More Muscle

Q: I recently went from training heavy on everything to [moderate-weight] 4X. I’m convinced that it’s genius. I gained four pounds in two weeks. My question is, What do you think of doing the first set heavy with low reps, then do a 3X after? That should get both size factors, right?

A: That’s a great variation. Of course, it’ll take a bit longer because you have to do some warmup sets. Then you do your heavy set, followed by a 3X sequence. We have a similar power-pump style of strategy in The Ultimate Power-Density Mass Workout…

In the Basic Workout, you do one exercise per bodypart. For example, for midback you do this: [Read more…]

Low Reps Plus Short Rests for Mass-Building Success?

Q: I’ve always gotten pretty good size and strength gains from heavy weights and using the six-to-eight-rep range. Could I be more myofibrillar dominant? And, if so, do you think I would benefit more by doing 4X mass training with lower reps, say 4×6, but still with short rests so that my sarcoplasm gets growth benefits as well?

A: Great question! For new readers, the myofibrils are the force-generating actin and myosin strands in the muscle fibers. If you have more of those than usual, you would be considered myofibrillar dominant. A good example of that is Mike Mentzer, who was squatting over 500 pounds at age 16…

Contract + elongate to pack on muscle weight

In most of our mass-training e-books we say that the semi-elongated, or stretch, position on an exercise’s stroke is most important to pack on muscle weight. Why?

Here’s a quote we used in The Ultimate Mass Workout from strength and hypertrophy researchers Steven J. Fleck, Ph.D., and William J. Kraemer, Ph.D. (Don’t fall asleep as you read it; we will translate—lol)… [Read more…]

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…]

Last-Set Shuffle to Pack On More Muscle

Q: I like the idea of doing something different on the last set of a 4X sequence. You mentioned a drop set, and that works great. What about a heavier pure-negative set? Like on curls my partner would lift it for me, and I would lower [a heavy weight] slowly for six negative reps.

A: That depends on what you’re trying to accomplish. Pure negatives—your partner lifts the weight, and you lower in six seconds—are designed to attack the force-generating myofibrils in the muscle fibers, which means they are primarily for strength building with only minor size effects, so not really building a lot more muscle… [Read more…]
