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…]
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…]
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…]
