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…]

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?

Doug Brignole doing a dumbbell decline press

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…]

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…

Change-to-Gain Mass Method #6

I’ve talked about these top-five change-to-gain methods over the past few newsletters…

1) Exercise switch
2) Altered rep speed
3) Stretch overload
4) More or less rest between sets
5) Exercise shuffle

The last one on my list is… [Read more…]

High Reps vs. Low to Grow

Scientific Training: Look Like a Bodybuilder

Jay Cutler doing spider curls

Q: After being involved in weight training for many years, and after working with many people as their instructor at home and at gyms, I think the main reason, and by far the most important one, that lifters get big and strong is because of their own personal genetics. How they train doesn’t make much difference. High reps, low reps, whatever. If they put even a little amount of effort in, they get big. Of course, drugs help immensely, but the actual type of training system they use is of little consequence, as long as it’s reasonably sound. I built 22-inch arms without drugs, and I performed a standing press with 400 pounds. I honestly do not believe it was because I trained scientifically. I did train hard, but it was because of my genetics that I gained so well and got so strong.

A: You are correct, but most trainees who are genetically gifted probably aren’t reading this. That’s too bad because by experimenting with science-based training, most of them could be so much better; however, because they gain easily, they think they’re doing things right and they keep plugging away with mediocre methods and never reach their full potential.

Low Reps Plus Short Rests for Mass-Building Success?

Q: I’ve always gotten pretty good size and strength gains from heavy weights and using the six-to-eight-rep range. Could I be more myofibrillar dominant? And, if so, do you think I would benefit more by doing 4X mass training with lower reps, say 4×6, but still with short rests so that my sarcoplasm gets growth benefits as well?

A: Great question! For new readers, the myofibrils are the force-generating actin and myosin strands in the muscle fibers. If you have more of those than usual, you would be considered myofibrillar dominant. A good example of that is Mike Mentzer, who was squatting over 500 pounds at age 16…

High Reps or Low Reps for Calf Mass and Vascularity?

Q: My calves suck. No size or veins whatsoever. Should I be hitting them with lower reps or high reps? Some people tell me up to 30 reps, others say I should go 10 to 12 reps with heavier weight. It’s so confusing… Please help!

A: Yes, the right calf-building recipe is tough for many people—but we have a good high-low method that could be just the trick to give you more calf mass, but let’s start with the science…

The Truth About Getting Stronger to Grow Bigger?

Jonathan squatting, dark room

We get the stronger = bigger question a lot—and there’s no question that getting stronger will build some size—note that we said “some.” To clarify, here’s an excerpt from our best-selling e-book The Super-Size Crash Course…

“One of the biggest reasons muscle growth is so slow in most cases is the simplistic myth that strength equals superior size. There’s more to it than that. Trying to move big weights for a few reps does very little for ultimate muscle size. Are you shaking your head? Check this out…
