Dedicated to Your Physical Transformation
Q: Do you believe that a person can max out muscle growth with 4X-style training considering you only use medium poundages?
A: We know for a fact that 4X-only workouts build a lot of muscle—and without straining joints because the poundages aren’t super heavy. Remember, with 4X you take a weight with which you can get 15 reps, but you only do 10; rest 30 seconds, then do 10 more; and so on until you do 4×10—and only the last set or two are to failure… [Read more…]
Q: I’ve been using your 4X method and throwing in some NA (negative-accentuated) sets every so often, mainly because I like some soreness. It makes me feel like I’ve done good work in the gym and am growing. Lately, I can’t seem to get much soreness from my workouts. Should I add sets or more NA or what?
A: There is no scientific research that shows that muscle soreness equals muscle growth—but we know what you mean. It makes you feel like you’ve hit the muscle hard enough to trigger growth, and it just makes sense that the microtrauma should translate into hypertrophy. We know for a fact that emphasizing the negative stroke of every rep can cause more soreness and that it can cause inflammation—which is temporary size. But that should lead to permanent mass… [Read more…]
Q: I’ve read a lot of your stuff over the years, especially when you had your daily training blog, so I have to ask: What’s the deal with squats? You’ve said before that they always injure you due to spine compression, and you’ll never do them again. But then I see them as the first quad exercise on leg day in some of your routines. You’re contradicting yourselves.
A: Not a contradiction; just another discovery. The way we used to do squats—building up to heavy weights over a number of sets with longer rests—produced more injuries than we care to remember. It was usually our lower backs that got jacked. As we found out the hard way over the years, having 350 pounds jamming down on your spine for even a few sets can do lots of cumulative damage. We’re living proof… [Read more…]
Q: I’m a big believer in Mike Mentzer’s Heavy Duty system of one all-out set to failure for each exercise. That’s why I think your 4X method is total B.S. Mentzer cited studies and found from personal experience that intensity is the key to muscle growth. With 4X you’re using lighter weights and not going to failure, which wastes a lot of sets. It can’t work, and I think you should feel ashamed for promoting it as miracle mass-building system.
A: We didn’t say it’s a “miracle” system (although some trainees have said it worked mass miracles for them). We simply said that we GUARANTEE that our 4X programs will build NEW MASS for just about anyone. We’re absolutely positive of that because it’s got ALL the critical components to trigger bigger gains quickly—and that includes intensity (we think Mentzer would agree as you’ll see, and that’s no B.S.)… [Read more…]
Q: I did all of my most recent workout with negative-accentuated sets as you suggested, and I’m very, very sore. Is that good for muscle growth?
A: Whoa! We never suggested doing an entire workout, every work set, in negative-accentuated (NA) style—that is, one second up on the positive and six seconds down on the negative. If you do all work sets that way, you will induce a lot of muscular trauma due to EXCESSIVE negative emphasis. The negative stroke induces the most soreness, so it will take many days to repair… [Read more…]
Q: What is the best rep speed for muscle growth? I want to look like a bodybuilder/physique athlete, so I’m not that concerned with strength. I just want more muscle mass.
A: In The X-traordinary X-Rep Workout e-book we cite a study that attempted to determine the optimal rep speed for building muscle. It compared doing sets with a two-to-three-second positive and a two-to-three-second negative—about three up, three down—with sets using a power cadence, which is one second up and three seconds down. The power cadence produced the most mass in this study. [Int J Sports Med. 30(3):200-204; 2009.] [Read more…]
Q: I’m using the Basic X-traordinary X-Rep Workout and making pretty good gains. I love that the workouts are quick and that I only use the Ultimate Exercise for each bodypart. My problem is that I think my gains could be even better because I’m not getting a big pump in some bodyparts. I do the density drop set on the Ultimate Exercise at the end, but most muscles just don’t pump like they should. Can I add an exercise to get more pumped? I have time.
A: That’s a common problem because everyone has muscles with low nerve force and/or fewer fast-twitch fibers. That makes getting a pump in those bodyparts more difficult, especially using only a big compound exercise. There are a number of things you can do, such as 10×10 style to end instead of a drop set, but we’ll give you something less time-consuming… [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…]
