Q: The Anabolic Reload Mass Workout, with a high-rep set first to fatigue slow-twitch fibers (STX), has helped me add six pounds of muscle in four weeks. Now I’m ready to go back to a three-way split, but the STX method worked so well that I want to keep using it, but after my heavy work. I’m in my 20s, so heavy weights is not a problem. Any suggestions? (Title: STX + SEX for Massive Muscle Growth)
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. ). 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. ).
Q: In The Ultimate Fat-to-Muscle Workout routines, you have short cardio sessions as optional after the workouts. Can I do the quick cardio before my weight-training workout to warm up instead of after?
A: You must’ve jumped right to the workouts without reading the text. No problem. We realize lots of trainees do that because they’re anxious to get started; however, there are important points in the text that can help you understand and get the best results from the workouts. The optional postworkout cardio session is a good example… [Read more…]
