Best Way to Train for Mass?

Scooter Guy

Q: The way you describe STX [a higher-rep set followed closely by a Speed Set] makes a lot of sense. But is it the best way to train for mass, or is it just the way you prefer to train? [Read more…]

Unreal 5-Week Muscle Gains

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…]

Small Details for Massive Gains

Q: I read Old Man Young Muscle 2 in one sitting. Amazing information. I’ve paged through the Exercise Guide, too. Great work. I’ll read that in full this weekend. The [new] Positions-of-Flexion stuff in it got my attention, so I’m excited. I did look at the triceps exercises closely because that’s a lagging muscle for me. Do you think the cross-cable pushdowns are better than dumbbell kickbacks for the contracted position? I’m desperate for more arm thickness. [Read more…]

It’s becoming more clear that training efficiency that avoids damaging your joints and muscles is best for the fastest mass gains as well as for your future health.

Here’s a quote from high-intensity advocate and former pro bodybuilder Mike Mentzer on that subject (Wayne Gallasch photo). [Read more…]

Failure Training and Faster Mass Gains

Q: I feel as though I need to train all of my sets to failure to get a good muscle-building workout. In Old Man Young Muscle, you take all of your sets to failure, but you’ve backed off of that. Why? [Read more…]

Fatigue, Failure, and More Muscle Mass (new research)

Arnold resting between sets...and looking huge

When confronted with study results that contradict something a trainee is doing, most will say, “Well, it works for me.”…

There’s something to be said for that response. Everyone is an individual and may respond to different methods. One example I’ve used in the past is rest between sets…

Speed Your Mass Gains

In a number of recent newsletters, I’ve mentioned the term “garbage negatives.”

It basically refers to the negative, or eccentric, stroke on a standard-tempo set. Lowering slowly is easy thanks to “friction” in the muscle—actin-myosin pairings “dragging” across one another… [Read more…]
