Mr. America Doug Brignole’s Training, Part 11

Doug found higher reps to be much more productive than lower reps, as you’ve seen from his 3-set approach: 30, 20, 12 reps.

This runs counter to much of what hypertrophy researcher Chris Beardsley recommends. Doug’s observations were about himself after decades of training experience, not a blanket recommendation for everyone: [Read more…]

How to Flip the Fast-Twitch Switch to Pack on Mass

Last week’s newsletter on fiber-type activation during a set was thought-provoking. If you missed that…

Unreal 5-Week Muscle Gains

Illustration showing where to perform X Reps on leg extension

Q: Excellent new ebooks. Your story about X-Reps and the gains you made in five weeks back in the day got me excited enough to try them. I didn’t realize what I was missing. I really feel those exercises working much better, and I’m already seeing results. Do you think the effectiveness of X-Reps will fade after a while? You mentioned [in the ebook] that it could be why you stopped doing them years ago. [Read more…]

Mass Mantra #35

Speed Sets—with 1.5-second controlled reps—are a big part of the Old Man, Young Muscle workout. Most of the top bodybuilders have been using them throughout their careers due to instinct—like Arnold.

Another is eight-time Mr. Olympia Lee Haney. Here’s what he had to say in a recent interview (photo by Michael Neveux)… [Read more…]

Mentzer’s High Intensity: Right or Wrong? Part 8

So training to all-out failure does get to the most fast-twitch fibers, but it also produces the most stress and damage, specifically on the last rep… [Read more…]

Moment of Bodybuilding Zen 214: Arnold’s Relaxed Mass

Here’s a rare security cam still of Arnold saying bye-bye to his blankie as a robber pillages his home. Luckily, the crook was caught, “Schnitzel” was found unharmed, and Arnold was able to sleep soundly once again… [Read more…]

High-Rep Pain to Gain Muscle?

Four pics of Jonathan to illustrate 4X

Q: I understand the benefit of the high-rep-set-first STX method. But for me the pain is unbearable when I get past 12 reps. Will 12 work to exhaust the slow-twitch fibers so that fast ones are better initiated on the second [lower-rep] set?

A: I feel your pain. It does hurt—and some trainees have a lower tolerance than others… [Read more…]

“Explosive” Mass Research Wrong?

Cyclists' quad development

Q: I read with interest your explanation of [researcher] Chris Beardsley’s take on explosive movements. If he’s right and the 2X explosive fast-twitch fibers don’t have hypertrophy potential and explosive actions can cause a transition of other type 2 fibers into 2X, how do we explain the muscular quads and calves of sprinters?

Fatigue, Light Weights, More Mass

Steve from the side in his backyard after 10 weeks of his diet

I’m often asked how I could possibly build muscle with only a 50-pound PowerBlock dumbbell set and a bench, as chronicled in Old Man Young Muscle.

It’s a common misconception that you need heavy weights to trigger hypertrophy—and besides, I had no choice… [Read more…]
