Double Your Muscle Growth With X-Factor Firepower

Incline barbell presses

Q: I’ve had phenomenal muscle-size gains and strength increases since switching over to X Reps. I gained five pounds my first month with them! My question is, Do those build more of the myofibril strands or sarcoplasm fluid [in the muscle fibers] that you guys have been talking about? And can I use X Reps on 4X sequences?

A: For the uninitiated, X Reps are eight-inch partials you do in the semi-stretch position at the end of a set to failure. For example, when no more full-range reps are possible on incline presses, you lower the bar to about two inches off your chest and fire up to just below the halfway point for about three to four controled X-Rep explosions… [Read more…]

Speed Reps—Quick Mass-Training Tip

Casey Viator flexing - Speed Reps—Quick Mass-Training Tip

Q: What’s your opinion of loosening exercise form at the end of a set to get a few more reps? Like on curls I keep the reps strict for the first six or seven, then I use some upper-body motion to complete two to three more reps. I’m using the 4X method, so the weight [throughout the 4 sets] is only moderate, not heavy. I’m only using momentum to fight the fatigue buildup at the end of the fourth set. Is that okay, or should I keep my reps strict through the entire 4X sequence?

A: Because the poundage is moderate on a 4X sequence, that’s all the more reason to keep it strict all the way through. Momentum will only take the tension off the target muscle. A very SLIGHT form alteration is acceptable, but keep it as strict as possible to the end of the fourth set… [Read more…]
