Should I Do More?

Q: I’ve noticed in a lot of your e-book routines that you often recommend just two work sets for an exercise Why? Should I do more? I’ve read that most bodybuilders do four or five sets per exercise.

A: As Arthur Jones, the creator of Nautilus machines said: “You can train hard or you can train long, but you can’t do both.” Short and hard or long and not so hard both work. Despite what some die-hard high-intensity trainers say, gradually increasing volume is a form of overload that can result in more muscle—if you don’t overdo intensity. It’s a balancing act. Us? Regardless of whether it’s one of our low-set workouts or high tension time workouts, we’re about efficiency of effort in the gym…

Testo-Jack, Hyper-Hypertrophy Workout

Q: I’ve been reading that testosterone is the key muscle-building hormone. Does the hormone boost come from intensity, more reps or what?

What that means is that you could train your legs hard and see size gains in other muscles, such as [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…]
