Q: It’s hard for me to believe that a few partial reps at the end of a set [a.k.a. X Reps] can do anything measurable for muscle gains. Isn’t doing an additional set just as good or better for muscle growth?
A: At first glance, you’d think so; however, once you understand muscle physiology, you see the enormous muscle-building effects that can occur if you extend a set correctly. It all starts with the size principle of muscle fiber recruitment…
[Read more…]Q: I’m making some incredible progress using your Double-X Overload technique, but I wanted to let you know that I don’t just use it on my work sets. DXO works for warmup sets, too. I usually use it on at least one of my two warmup sets for the big [midrange] exercises. I feel much stronger on my work sets. Great technique!
A: That’s a good tip. We love feedback from fellow weight trainers who think instead of just following the pack. One reason DXO works so well on warmup sets is because of the enhanced occlusion and nervous system activation.
[Read more…]Q: The idea of a few medium-intensity [subfailure] workouts after many weeks of going all out makes perfect sense to me. My question is, Should I reduce my poundages so I can do the same number of reps, or should I stick with my same working poundages and just do fewer reps? Which way is best?
A: We prefer to use the same phase-training approach Jonathan used on the 10-week Size Surge Program when he gained 20 pounds of muscle. For each of his two supercompensation weeks, he used the same work weights and just stopped two reps short of failure—and that worked amazingly well for him. He actually appeared to get bigger during each downshift week as his muscles and nervous system
Q: I’ve been intrigued by your explanation of workout density being the reason your 10×10 program builds mass. Do you think that’s the reason drop sets are also so effective?
A: Workout density is Vince Gironda’s term to express getting more work done in a given time frame. For example, most trainees do a set, rest for two to three minutes, do another set, and so on. In 10 minutes you only do two or three sets…
[Read more…]Q: I was reading some past articles where you guys had mentioned something called Aftershock training. What is that, and should I try it?
A: Aftershock training is supersetting two exercises, but with a distinct reason—more fast-twitch fiber recruitment for new muscle growth quickly (it can rejuvenate standard straight-set 3D POF training, as you’ll see).
[Read more…]Q: I have a hard time feeling some of my muscles working, especially short-range ones like abs. Should I go heavier, lighter, slower, or what? I know feeling the target muscle working is very important for the fastest results.
A: You can say that again. Getting in touch with the target muscle on every rep is a big key to muscle hypertrophy…
[Read more…]Q: I’m testing your 4X variations [Shock-centric, 4X Pyramid, etc. from one of your recent newsletters]. Great stuff! Isn’t another way to get more mass simply to add sets by increasing the volume to 5X or more on any exercise?
A: Yes, volume increases, as in tacking on sets to 4X so you’re doing 5X or 6X, can boost mass gains—to a point. It’s a lot like tanning: To get darker, you can increase exposure time. The problem is diminishing returns… [Read more…]
A: You do one set to positive failure, to prime your nervous system for optimal firing with a heavy weight. Rest about two to three minutes if it’s a big compound exercise (multi-joint; rest a little less on isolation moves), then perform a second set to nervous system exhaustion with X Reps added to the end—no break; as soon as you can’t do another full-range rep, move to the X spot and crank out partials for max growth stimulation. Your second set, with X Reps, is the money set—that’s where you’ll get the most mass stimulation for your efforts. You’ll feel it happening, believe us!
That being said, we have had reports of great success from some trainees who are doing X Reps on the first set and then using the second as a burnout set with less weight. You may want to experiment with that method as well.
A: Yes, X Reps are better because you extend the set at only the precise point in the exercise’s stroke that is key for force production and/or fiber activation. With forced reps, on the other hand, you writhe around as you strain through full range reps with help from your training partner. So while X Reps help you circumvent nervous system failure for an extra hypertrophic surge, forced reps waste a lot of nervous energy as you push through weak areas of the stroke with imprecise unloading (pushing or pulling from your partner). That’s why trainees who use a lot of forced reps tend to get tremors after training—they overstress the nervous system.
A recent study appears to confirm that (International Journal of Sports Medicine, 24:410-418. [2003]). It featured 15 male athletes engaged in either a maximum-reps routine or a forced-reps routine. Both types of training led to considerable increases in serum testosterone, free testosterone, cortisol and growth hormone; however, cortisol, which is a stress hormone that can cannibalize muscle tissue, was higher in the forced-reps group. Forced reps also produced a greater decrease in maximum muscular force, according to the researchers.
The greater loss of muscle power indicates that forced reps overstress the nervous system and the excess cortisol produces catabolism in muscle. In fact, many studies indicate that the biggest cause of overtraining is nervous system stress, and therefore forced reps do a lot to increase that probability—much more than X Reps. In other words, cue to X Reps short stroke, as opposed to full-stroke forced reps, we believe X-Rep training is a superior way to extend a set for a maximum growth response with less recovery and nervous system stress (Journal of Applied Physiology, 85:2352-2359. [1998]).
Q: You guys don’t seem to like training each muscle only once a week like a lot of pro bodybuilders. How come?
A: More muscle-training frequency is a BIG size stimulator, especially for drug-free trainees—if you do it correctly. Many pros can get away with training each bodypart with excessive volume only once a week because of genetic superiority and, of course, excessive drug use. In fact, if you look back at the best bodybuilders of yesteryear, when steroid use was minimal, training each bodypart THREE times a week was the norm prior to a contest. It’s a bit of a forgotten muscle-size trick… [Read more…]
