Repping High to Low to Grow

Steve demonstrating cable lat pull-ins and cable chest press

Q: I’m seeing a lot of new growth since I’ve been using Speed Sets [on “set 2” after the first 1/3-tempo primer set]. I notice a fluctuation with some muscles. Like on cable lat pull-ins I can get 8 to 10 Speed Reps, but on cable chest presses I only get 5 Speed Reps. Is that a lack of reps slowing my gains? [Read more…]

End With Higher-Rep Set for More Mass?

Q: You make a good case for doing a higher-rep [15-to-20] set first to failure. Getting all of the fiber types to “red line” right off the bat when you’re fresh has built new muscle for me. The Speed Set after, to bring in more key [fast-twitch] growth fibers, also works as a motivating change of pace. But I’m wondering, what if you do some standard heavy 8-rep sets first and end with that higher-rep set to failure? Won’t you accomplish the same thing? [Read more…]

More Muscle Girth With This…

Q: I’m growing again with STX. But I was thinking that instead of 15 to 20 reps on set #1, how about getting to the fast-twitch fibers faster with a heavier 8-rep set instead? Then lighten the weight and do a Speed Set for even more fast-twitch stimulation.

A: The higher-rep initial set is more efficient, safer and better for hypertrophy—especially for older trainees—for a few reasons… [Read more…]

Low Reps, Less Damage, More Growth?

Steve demonstrating lat pull-ins with cables

Q: I recently saw [hypertrophy researcher] Chris Beardsley say that high reps cause more damage than low reps due to calcium-ion accumulation from fatigue. Does that make you rethink the STX method? Maybe doing the first set heavier with lower reps for less damage would be better? [Read more…]

Fewer Reps, More Mass?

Q: After my 20-rep set with a 1/3 tempo on the ideal exercise, I rest 20 seconds, then do a Speed Set (1.5-second reps) on that exercise. You say that you get 10 or fewer Speed Set reps, but I get 13, sometimes more. Should I cut my rest down to 10 seconds so I get fewer reps on my Speed Set? [Read more…]

High-Rep Pain to Gain Muscle?

Four pics of Jonathan to illustrate 4X

Q: I understand the benefit of the high-rep-set-first STX method. But for me the pain is unbearable when I get past 12 reps. Will 12 work to exhaust the slow-twitch fibers so that fast ones are better initiated on the second [lower-rep] set?

A: I feel your pain. It does hurt—and some trainees have a lower tolerance than others… [Read more…]

Q: I’ve always thought that lower reps were for mass. Do I need high reps at all? Don’t they just deplete recovery and inject inefficiency and fatigue into hypertrophy workouts?

A: Just the opposite for most trainees. I say “most” because there are a few fast-twitch-dominant people on one end of the Bell Curve who thrive on low reps. But consider this study (Mitchell, et al. 2012)…

Trainees did three sets of leg extensions to failure three times a week for 10 weeks. And each leg was trained differently…

One leg used 80 percent 1RM (lower reps), while the other was trained with 30 percent 1RM (higher reps)…

Quad growth was excellent but not different between legs. The interesting part was…

It appeared that the heavy-load training grew primarily the fast-twitch fibers, while the light-load training increased type-1, or slow-twitch, fiber size. Remember, there was no difference in hypertrophy response…

No doubt all fiber types grew in both legs; however, heavy leans fast-twitch and lighter leans slow-twitch—because of so many preliminary reps…

Would a mix of high and low reps yield even better results? My guess would be yes…

It’s only one study, so more research is needed; however, it appears to confirm that using a variety of rep ranges can produce hypertrophy in multiple fiber types for more overall mass.

And that’s one of the key reasons I include rep ranges from 20 down to 8 in Old Man, Young Muscle over three to four sets per muscle. It works…

As I mention in OMYM (page 44), respected researcher Jerry Brainum recently said that “It’s now known that type-1 [slow-twitch] fibers are capable of showing a significant level of hypertrophy, more than previously believed.”

So including a higher-rep set or two can provide another layer of mass. And let’s not forget that a high-rep set first can trigger more fast-twitch activation on the sets after due to slow-twitch exhaustion (STX).

Specialize for Massive Size

Specialization training is when you devote your time and attention to building up a particular lagging muscle group or set of muscle groups.

Most guys in the gym use specialization to build bigger “visible” muscles like arms, forearms, or calves, but little do they know that they’re wasting countless sets and reps…

Plus, they initiate no growth hormone response—meaning all their specialized sets are basically worthless!

Instead of wasting effort, you can pack on slabs of muscle mass FAST while skyrocketing your testosterone levels to pave the way for even FASTER muscle growth through Alpha-3 Specialization.A

But instant results aren’t the only perk of Alpha-3 Specialization…
