Study: Pounds of Muscle After One Workout (Yes, One Workout)

Q: In the “X Factor” interview at X-Rep.com, Jonathan says you guys tried a static contraction at the end of isolation exercises with only mediocre size results. But I just got the X-Rep Update #1 e-book, and you’re recommending them. Why have you found static holds more effective now than in the past?

A: When we first used static contraction many years ago, we did them on contracted-position exercises, like leg extensions, holding the flexed position for as long as we could after full-range exhaustion. That’s a hold after a number of regular reps. We got good gains, but later that hold at the end of a set evolved to X Reps on the big midrange exercises instead of isolation moves, and that worked much better at building bigger, fuller muscles.

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…

Study: Forgotten Muscle-Mass Trigger

It’s becoming clear that muscle elongation is very important for accelerating hypertrophy to a new level.

In other words, loaded stretching can provide another layer of freaky size quickly.

An older study that we often reference showing that was performed by Jose Antonio, Ph.D., et al.—and it produced incredible muscle size increases. Here’s what he said about it: [Read more…]

Study: Fast Reps for More Mass? (Plus the 8-10-8 Method)

It’s always interesting to see studies that come out on muscle activation with varying protocols. One of particular interest is from the National Strength & Conditioning Association [May 29, ’15]…

It compared two protocol, but with the same time under tension and load, 60 percent of 1-rep max. The exercise was Smith-machine bench presses, and the subjects were experienced resistance trainers… [Read more…]
