Max-Muscle-Size Study: Rest Between Sets—is short or long best?

Q: Your 4X mass method has 35 to 45 seconds rest between sets. I’ve seen research that longer rests between sets can be better for strength and muscle growth. What’s your take on that?

A: Legendary trainer Vince Gironda, the Iron Guru who trained Mr. Olympias as well as Hollywood stars to build muscle fast, first got us into reducing rest between sets for muscle growth—he called it Density Training…

Try This for New Growth Fiber Activation and Muscle Expansion

Jonathan Lawson leg extensions - Try This for New Growth Fiber Activation and Muscle Expansion

Q: I’ve been using MMX Compound Aftershock [from a recent newsletter]. The high-rep stretch exercise first, before the big compound move, really makes a difference. What a great burn and pump. If I use a high-rep contracted-position move first, is that postactivation?

A: Yes, you could consider it postactivation, as it too increases growth-fiber recruitment on the second big exercise. So for quads, Compound Aftershock would be high-rep sissy squats followed by a superset of lower-rep sissies and squats… [Read more…]

The ultimate change-to-gain tactics for muscle size

Leg presses, bottom

Q: I get confused. Should I try to change exercises at every workout to keep my muscle adapting and growing?

A: The problem is that your body really needs to adapt to a movement pattern over the course of a few workouts before you change exercises—at least that’s the theory… [Read more…]

Muscle-Building Myths—Or Are They? (controversial muscle-building info)

Dumbbell flyes showing thick pecs - Mass-Building Myths—Or Are They? (controversial muscle-building info)

Q: I heard that close-grip bench presses can build the inner pecs. But then a pro bodybuilder said that’s false. He said no exercise can build the “inner” pecs—or “lower” biceps for that matter, and that those are muscle-building myths. Which is correct?

A: While close-grip bench presses won’t direct development to the inner-chest area, some researchers suggest that putting a muscle into elongation, or stretch, against resistance can thicken the fibers at the insertion point. For example, doing flyes for more chest beef near the sternum… [Read more…]

Should You Skip Triceps Work?

Jonathan Lawson doing overhead dumbbell triceps extensions

Q: I was reading that because most bodybuilders do a lot of pressing, they shouldn’t do much direct triceps work. I do bench presses and incline presses for chest and overhead presses for shoulders, so isn’t that enough work for my triceps? I’m drug-free, so I don’t want to overtrain them.

A: Two things to consider:

1) MRI studies show that bench presses and overhead presses do hit the triceps, but mostly the medial and lateral heads; in other words, the bulkiest section of the triceps, the big long head, is almost totally neglected. [Read more…]

Testo-Jack, Hyper-Hypertrophy Workout

JL Homegym Squats - Testo-Jack, Hyper-Hypertrophy Workout

Q: I’ve been reading that testosterone is the key muscle-building hormone. Does the hormone boost come from intensity, more reps or what?

A: Arthur Jones, creator of Nautilus machines and the overseer of the Colorado Experiment that saw Casey Viator gain 60 pounds of muscle in only 4 weeks, always said that training legs hard can have a big “indirect muscle-building effect.”

What that means is that you could train your legs hard and see size gains in other muscles, such as [Read more…]

Study: This quick hit can double your muscle growth

J.L. Incline Curls Stretch Position - This quick hit can double your muscle growth

Dr. Jacob Wilson, who used to write for Iron Man when we worked there, recently performed a study with a technique we have recommended over the years—stretch holds, or Stat-X.

Dr. Wilson calls it “intraset stretching.” In his study, the subjects who included intraset stretching DOUBLED muscle thickness compared to those who did not use it. Amazing. [Read more…]

Quick-Rep Modification for New Mass Acceleration

Q: I have your new ebooks, Anabolic Reload and Stretch Overload. Both are great, and the simple rest/pause add-on for progression has already helped me add new mass. But I overtrain easily, so I can’t keep adding those. Is there anything else I can do to keep my muscle growth moving forward without more volume?

A: First, bodybuilding is called “progressive-resistance” training because adding weight and/or reps to your exercises can increase muscle size… [Read more…]

STX + SEX for Massive Muscle Growth

JL Arm Muscle Fibers - STX + SEX for Massive Muscle Growth

Q: The Anabolic Reload Mass Workout, with a high-rep set first to fatigue slow-twitch fibers (STX), has helped me add six pounds of muscle in four weeks. Now I’m ready to go back to a three-way split, but the STX method worked so well that I want to keep using it, but after my heavy work. I’m in my 20s, so heavy weights is not a problem. Any suggestions? (Title: STX + SEX for Massive Muscle Growth)
