As many of us already know, studies have shown that whether you use 30% of your 1RM or 70% of your 1RM, gains are virtually the same, so long as you take your sets to or close to failure. So one may conclude that using either method is best for bodybuilding for the long term. But let's think about this further:

A six-rep set won't get you as much of a pump as a 12-rep set.

If a pump responsible for sarcoplasmic "growth," via metabolic stress, then wouldn't we be missing out doing lower-rep sets? One way to that I've learned to get a pump with six-rep sets, is to do more sets: like five sets of six, which is a total of 30 reps. But does this achieve the same as three sets of 12, which his 36 reps?

A six-rep set will be more strenuous on your joints/tendons than a 12-rep set.

I find that extension movements are more prone to pain than curling movements; so in this thought experiment, lets take one-arm overhead dumbbell triceps extensions.

A six-rep 35lb dumbbell extension will certainly put more stress on your elbows than a 12-rep 20lb dumbbell extension; even with proper warm up, you can feel the tension on the elbow much more. In fact, many people like to warm up with cables before doing skull crushers and others movements, so they can get away with using less weight.

Most injuries seem to come from using heavier weights.

From all the tears I've seen on video, and the stories shared by the pros, injuries were caused by using heavy weights. Although it is certainly possible to tear a bicep or blow out your back doing some simple chore at home, like picking up a couch, virtually all of the videos I've seen of gym injuries have been with heavy sets.

Conclusion:

So with all this being said, wouldn't it make more sense for bodybuilders not to do heavy sets at all, and just stick to the "safer" 8-12 rep rage? Of course the term "heavy" is also relative, so it is hard to determine it for each person, but the six-rep range I would consider "heavy."

However, lately I've been experimenting with lower-rep sets, doing the 4-5 sets of 6-8 reps, but I'm using super-short rest periods of 45 seconds to a minute max, with ample warm up sets; so the "heavy" weight I'm using, is actually much lighter than what I could be using, had I rested longer. In this way, I get a pump, but I also don't have to fatigue myself as much doing higher rep set for exercises that would tax my CNS. I for one love to push hard, but I also love the pump, so in this way, I get the best of both worlds, without getting injured. I've never been injured before (aside from a 130lb dumbbell dropping on my big toe), and I don't plan on it, either.

I got this idea watching Jay Cutler, who said in a video that he uses very short periods, and thus, has to use "heavier" weights and more sets to get that volume. He also said, if he can't do eight reps, he doesn't touch it.

The reason why I ran into Jay, is because I was researching who are the least injured bodybuilders out there, and it seems to me, those who are least injured trained not as insanely heavy as those who are utterly destroyed today—Branch/Ronnie/Dorian etc. We see guys like Dexter, who I don't think has ever gotten injured at all, pumping along in their 50's lol. So there must be something to that kind of training.

So, doesn't it make sense that the safest ways to workout would either be to do higher-rep sets with longer rest periods, or lower-rep sets with shorter rest periods to make the weight "relatively" heavy, so in both cases you get the same "volume" in the end without the risk, instead of using heavy ass weights with longer rest periods, as if we were powerlifters, trading super-intensity for less volume in the end?

Just some thoughts to throw out there.

I agree with what you wrote, especially as an older guy. I aim for 10-15 reps in general, which means a bit lower weight.

Higher risk of tendon injuries by using heavier weight / lower weights. My shoulder tear was from higher weight (3 rep max).

I also personally find it easier to have multiple reps close to failure when I use higher reps. The fatigue is building up more slowly, several of the last reps feel close to failure. With high weight, I kind of hit the wall, no fucking way I'll get another rep. With lower weight, i may squeeze out 1 or 2 more. On the assumption that it's those reps close to failure that really counts, that trigger hypertrophy.

Guys have become big size on both high rep and low rep programs, but above reasons are primarily why I personally prefer higher reps.

I am really not sure whether the pump actually contributes to hypertrophy or just limits max output. Mega pump in lower arms until you barely can hold the pull-down bar certainly doesn't help.

Look forward to hearing opinions of more knowledgeable people.
 
Moderate weight is the way forward.....not heavy or light....but using continual progressive overload techniques to stimulate more growth and more gains.

"Heavy" just leads to injuries and periods when you can't even train.

"Light" just means you're wasting your time in the gym doing semi-cardio sessions and not hypertrophy training.

"Moderate" means you are training intelligently but whilst still also challenging your body and making muscle gains.

According to the research, Dr. Mike Israetel said rep ranges from five to 30 can stimulate hypertrophy. Yes, I was shocked to hear 30 as well.

Sounds like bullshit research to me and just yet another "expert" talking nonsense about llifting weight/building muscle.

What outcome can any of us reach from such a wide scope of rep ranges (5 to 30) and without even considering somatotypes and lots of other individual and personal variables?

Advise an ecto to hit 30 light reps per set for growth and see what happens :rolleyes:

Advise an endo to hit 5 heavy reps per set and see what happens :rolleyes:
 
Personally I have always responded better to lifting in the heavy 6-8 rep range. I can't do heavy weights for months on end because I will eventually stall out. To prevent stalling I rotate every 10-12 weeks between heavy weight low reps to moderate weight higher reps. This method works great for me personally.

You make really good points about heavy weights and injuries though. I haven't had one yet(knock on wood) but as I get older it is on my mind alot. I'm sure I will eventually back down on the heavy weights.

4-8 and 10-15 are both intelligent "moderate" training intervals and IME always yield the best results if you adjust the weight for each style of training.

Focusing on heavy numbers (i.e 1RMs) is just dumb and pointless.

From what I understand entire endo, meso, and ectomorph thing was debunked.

In regards to 30 reps; they MUST be taken to near/failure, otherwise they would absolutely be useless.

He didn't do the research, he is repeating what has been shown in the meta analyses.


Research by Brad Schoenfeld, he's not some random guy; he is one of THE guys leading exercise science.

Follow your beliefs and the experts that don't even lift weight/train bro. That's all I can say to you. Good luck.

The idea behind the pump is it stretches the muscle facia allowing for sacroplasmic or even tissue hypertrophy to happen easier. Essentially the more pliable the muscle sack is the less it is constricting down. May not end with the hardest muscles if you do sarcroplasm growth mostly but size will be easier to get to. Theoretically
 
30 reps a set would be mid rep range for me on some things. I often do sets of 50 or even 100, no bullshit. I’ll open up on a chest press machine with 100 reps right from the jump, then rest a few minutes and do 3 more sets of 8 reps/set going heavier and using 10 sec negatives on every rep. It all works for me, it all comes down to given units of work in a certain time frame. But those high rep sets are pump type sets, no way in hell I can do slow negatives on a set of 50 or 100 reps.

But what I often do is fail at a light weight first, then go up in weight on additional sets

Interesting.

The more I research into this, it seems the only thing that really matters is getting to or very close to failure; everything else is preference.

Bullshit bro.......but I hope you have fun doing 30 rep curls to failure with 10kg coz that's what your research told you to do.

If 30 isn't enough for failure...maybe try 50 or 100 reps.
