The Stretch-Strength Link

Q: I’m loving the 3D HIT program [listed in the X-traordinary Arms e-book]. Every bodypart is growing, my strength goes up at almost every workout, and I’m only in the gym for 45 minutes. So far, it’s sweet! My question is, Shouldn’t the stretch exercise be last in the 3D sequence: midrange, contracted, then stretch? I’ve read that stretching a muscle makes it weaker right after, so it only makes sense that you should do the stretch-position exercise last instead of before the contracted-position exercise; otherwise, you’ll be weaker on the contracted move. Am I off base here?

A: Either order works well for stimulating growth, and it’s good to mix it up for more adaptation (growth). But we’ll give you our reasoning for why we think the standard order (see the pics below) is best for optimum hypertrophy (fast mass) with regard to the stretch-strength link. Take biceps as an example. The standard 3D POF program is barbell curls, incline curls, and concentration curls—in that order. [Read more…]

Best Mass Moves for High-End-Hypertrophy Hits

Q: I just started using the 30-20-15 [TORQ] method on one exercise for each muscle. I do the other exercises as regular sets or 4X. The higher reps really feel incredible. What a great pump and deep fiber hit. My question is, Which exercise is best for 30-20-15—midrange, stretch or contracted?

A: As we’ve mentioned before, the angle of pull is different on each of midrange, stretch, and contracted exercises, so fiber activation can be unique as well.

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…]

More Mass-Building Myths Busted (logic or looniness)

Q: I read where old-school bodybuilders would use lighter weights and higher reps on some exercises before competition to get more muscle detail. That’s total B.S., right?

A: On the surface, yes. But ending a bodypart with higher-rep work—or even doing entire workouts with higher rep work, enhances muscle burn. No, that’s not fat burning—at least not in a strict sense… [Read more…]

Muscle Expansion With Isolation

Q: Isn’t it true that you activate the most muscle fibers in the flexed position, like at the top of a leg extension or leg curl? I know that [Nautilus creator] Arthur Jones said that. So shouldn’t I really flex at the top of those isolation-type exercises? Come to think of it, why should I do compound exercises [like squats] at all? Isolating the muscle appears to be the logical way to stimulate the muscle growth best.

A: We respect the late Arthur Jones and value much of his research, theories, and opinions (Steve met him many years ago in Florida); however, newer research states the contrary—that the contracted, or flexed, position of an exercise is not where the most force/fiber activation occurs—it’s the bottom, where the target muscle is somewhat stretched. Here’s a quote from respected scientists Steven J. Fleck, Ph.D., and William J. Kraemer, Ph.D., that makes the point (we’ll put their statements in simpler terms in a moment): [Read more…]

New 3D HIT: More Muscle, Less Time?

Q: I’ve been checking out a lot of the high-intensity-training (HIT) stuff on the Web. Using one all-out intense set per exercise makes a lot of sense. But doing only one exercise per bodypart, as in most HIT programs, does not make sense to me. That’s why I want to try the more abbreviated HIT approach combined with 3D POF [training each muscle in three positions for full-range activation]. Any suggestions?

A: What you’re talking about is a key reason 3D Positions of Flexion evolved. It attacks the full contractibility range of a muscle for maximum fiber recruitment as well as [Read more…]
