How Many Sets Do You Really Need to Build Muscle?
Summary
TLDRトレーニング量と筋肉成長の関係について説明した動画スクリプトの要約です。研究によると、筋肉1個あたり週に10セット以上行うことが最適な筋肉成長につながることが分かっていますが、さらに多くのセットを行っても成長は大きく増加しないとされています。また、個人差が大きいため、自分に合ったトレーニング量を見つけることが大切です。フォームを守りながら失敗に近いトレーニングを心がけると、少ないセットで効果的な結果を得られるとされています。さらに、休憩時間の長さや、筋肉を直接的に刺激するセットの数など、他の要因も考慮する必要があります。初心者は10セット程度から始め、経験を積むことで徐々にトレーニング量を増やしていくことが推奨されています。最適なトレーニング計画を見つけるための無料のトレーニングプランも提供されています。
Takeaways
- 💪 重量トレーニングにおけるセット数と筋肉成長の関係は、セット数が増加することで筋肉成長も向上するというドーズ応答関係があることがわかりました。
- 📈 2017年の研究によると、1セットから5セット、5セットから9セット、そして10セット以上と比較して、10セット以上のセット数が最も成長を促進することが示唆されています。
- 🔄 しかし、その後の研究では、10セットから20セットまでのセット数で筋肉成長が向上した一方で、20セットを超えると成長促進効果が見られなかったため、ボリュームの最適な範囲は10セットから20セットと考えられるとされています。
- 🚫 高ボリュームトレーニングは、回復問題のために成長を阻害する可能性があるため、個々の状況に応じて適切なセット数を設定することが重要です。
- 👤 個人差が大きく、一部の人々は低ボリュームで良い結果を得られる一方で、他の人々は高ボリュームが必要とする可能性があるため、自分に合ったトレーニングボリュームを見つけることが求められます。
- 🏋️♂️ トレーニングの実行には、フォームの維持が重要で、失敗に近いところでトレーニングを続ける必要がありますが、フォームが崩れるまで行う必要があります。
- ⏰ セット間の休息時間が短い場合は、同じ成長効果を得るためにより多くのセット数が必要になることが研究から示されています。
- 📉 セットをカウントする際には、間接的にトレーニングされる筋肉も1セットとしてカウントされることが多いため、実際に必要な直接セット数は減ることに注意する必要があります。
- 🏅 ハイインテンシティトレーニングは、1セットで失敗を超えるトレーニングを行っており、通常の2セットから3セットに匹敵する筋肉刺激を与える可能性があります。
- 🎯 経験不足な初心者は、10から20セットの範囲の低いほうのセット数から始めることが推奨されますが、経験を積むことでボリュームを増やすことができます。
- 📚 トレーニング計画を選ぶ際には、睡眠、食事、トレーニングの強度、フォームの維持など、個人の状態を総合的に考慮することが大切です。
Q & A
2017年の研究で見出された筋肉成長とセット数の関係は何ですか?
-2017年の研究では、筋肉成長とセット数の間にはドーズ応答関係があることが発見されました。1セットから5セット、5セットから9セット、そして10セット以上の比較を行っており、10セット以上のセットが最も成長を促進することがわかりました。
筋肉量を増やすために必要な理想的なセット数はどれくらいですか?
-理想的なセット数は、筋肉1個あたり週に10セットから20セット程度と考えられています。ただし、個人差があり、最適な数は個人によって異なるとされています。
トレーニングのボリュームが多すぎると、どのような問題が発生する可能性がありますか?
-トレーニングのボリュームが多すぎると、回復の問題が発生し、成長を妨げる可能性があります。また、過剰な疲労や筋肉損傷を引き起こして、回復を妨げることも考えられます。
トレーニングで正しいフォームを保つことがなぜ重要ですか?
-トレーニングで正しいフォームを保つことで、筋肉をより効率的に刺激し、失敗に近い状態までトレーニングできるため、セット数を減らしても同じ成長を得ることができます。また、フォームが崩れると、刺激が十分に届かなくなります。
セット間の休息時間を長くする理由は何ですか?
-セット間の休息時間を長くすることで、筋肉はより多くの休息を得ることができ、より強力な刺激を与えることができます。短い休息時間をとる場合よりも、同じ成長を得るためには多くのセット数が必要になるという研究結果があります。
三頭筋が高ボリュームに応答する理由は何ですか?
-三頭筋は他の筋肉と比べて、他のトレーニングで間接的に働かれる頻度が高いため、高ボリュームでトレーニングすることでより良い結果が得られる傾向があります。
1セットで筋肉を失敗に近い状態までトレーニングするというハイインテンシティトレーニングの利点は何ですか?
-ハイインテンシティトレーニングでは、1セットで失敗に近い状態までトレーニングを行い、力尽きた reps、rest pause reps、またはdrop set reps を使用して、追加の動きが不可能になるまでトレーニングを続けます。これにより、通常の2~3セット分と同じ刺激を得ることができます。
トレーニング量が少なくとも十分だと示されている筋肉1個あたりの最低セット数はどれくらいですか?
-筋肉1個あたり週に3セットのトレーニングで筋肉を増やすことができるという研究結果があります。経験豊富な個人では、1セットで十分な刺激を得ることができる場合があるとされています。
トレーニング計画を始める際のアドバイスは何ですか?
-初心者は10セットから20セットの範囲の低いほうの週に10セットから始めることをお勧めします。経験を積むにつれて、ボリュームを増やしてみることができますが、効果がなくなってきた場合は、トレーニングの質や食事、睡眠をチェックし、必要に応じてセット数を増やしたり減らしたりする必要があります。
トレーニング計画をカスタマイズするにはどうすればよいですか?
-builtwithscience.comで提供されているクイズに答えることで、自分に最適なトレーニングプログラムを見つけることができます。また、buwis si.com slf freework workoutsから無料のトレーニング計画をダウンロードすることもできます。
トレーニングで使用するセット数の目安として、筋肉1個あたり週に10セットから20セットを提案されている理由は何ですか?
-その範囲のセット数は、多くの人々が筋肉成長を促進するのに十分であり、個人差を考慮しても最適な結果を得られる可能性が高いからです。また、より少ないセット数で十分な成長を得られることから、初心者や忙しい人にとっては手が届きやすいトレーニングプログラムになる可能性があります。
Outlines
💪 筋肉増強のセット数に関する研究
筋肉を増強するために必要なセット数は、人々によって意見が分かれる。一部は1セットだけ行い、失敗に至るまで行うことが最善だと主張し、他の人々は4~5セットを推奨する。2017年の研究では、1セットから10セット以上のセット数と筋肉成長の関係を比較し、10セット以上のセットが最も成長を促進することが分かった。しかし、その後の研究では、10セットから20セットまでの範囲で最適な結果が得られることが示された。また、個々の対応、トレーニングの実行方法、セットの回数、およびトレーニングの強度など、他の要因も考慮する必要がある。
🏋️♂️ セット数の最適化とトレーニング方法
トレーニングの実行方法は、必要なセット数に大きな影響を与える。短い休憩時間(2分未満)であれば、同じ成長を得るためにはより多くのセットが必要とされる。また、セカンダリ・ムスルのセット数をどのようにカウントするかも重要であり、ベンチプレスでは胸と三頭筋に1セットずつとカウントされる。しかし、実際に必要なのは直接的なセット数であり、胸全体に週に10セット程度が必要で、これを異なるトレーニングで分割することが望ましい。また、トレーニングの強度にもよりがちで、1セットを完全な失敗まで行うことで、通常の2~3セットと同じ刺激を得られる。
📈 最適なトレーニング計画の選択と進化
初心者は週に10セット程度のトレーニングを始めるべきであり、その後、経験を積むことで徐々にトレーニング量を増やすことができる。トレーニング効果が停滞している場合は、睡眠、食事、トレーニングの強度を再度チェックし、必要な場合はさらにトレーニング量を増やす。また、ビデオの最後に、3つのトレーニング計画が提供されており、週に6セットから14セットまでのトレーニングが含まれている。さらに、自分に合ったトレーニングプログラムを見つけるためのクイズも提供されている。

Highlights
The optimal number of sets for muscle growth may be less than commonly believed, with a sweet spot between 10 to 20 sets per muscle per week.
A 2017 study by Brad Schenfeld found a dose-response relationship between muscle growth and the number of sets, with 10+ sets per week showing the most growth.
More recent research suggests there might be an upper limit to the number of sets, beyond which additional volume does not lead to more growth and might even hinder it due to recovery issues.
Individual response to training volume varies, with some people responding better to lower volumes and others to higher volumes.
Exercise execution and maintaining good form are crucial when training close to failure, which can reduce the number of sets needed.
Longer rest periods between sets can allow for a lower volume approach while still achieving growth.
The triceps are an exception, responding better to higher volumes, but this might be due to how sets are counted in research.
Indirectly worked muscles, like the front side and rear delts, may not need as many direct sets due to the frequency of their indirect training.
High-intensity training, such as performing sets beyond failure with techniques like forced reps or drop sets, can provide a similar stimulus to multiple sets.
For beginners, starting at the lower end of the 10 to 20 weekly set range is recommended to avoid overloading the body.
Consistency is key, and even fewer sets can lead to good results if done with proper form and intensity.
If progress stalls, a flowchart from the Muscle and Strength Pyramids book can help determine if more volume is needed or if recovery is the issue.
Even just three sets per muscle per week can build muscle in trained individuals, indicating that volume can be significantly less than what is typically prescribed.
The video concludes with a free minimalist and optimal workout routine for viewers, which takes into account the scientific findings discussed.
A customized workout plan can be obtained by taking a quiz at builtwithscience.com to find the best program for individual needs.
The presenter emphasizes the importance of not just chasing optimal volume but doing what is sustainable and effective for the individual.
Transcripts
how many sets do you really need to
build muscle some say just one set taken
to all o failure is best whereas others
preach high volume doing four to five
sets per exercise and taking over 3
hours to complete a single workout who's
right and more importantly how many sets
should you do especially as a natural
well the answer might surprise you and
is probably a lot less than you're
currently doing the first major analysis
on how the number of sets you do affects
muscle growth was done in 2017 led by
researcher Brad shenfeld they compared 1
to 5 5 to9 and 10 plus sets per muscle
per week so for example six weekly sets
for the chest could be three sets of
bench and three sets of flies now what
they discovered is a dose response
relationship between muscle growth and
the number of sets per form with 10 plus
sets per muscle per week resulting in
the most growth after this met analysis
was published pretty much all of us
Fitness nerds were under the impression
that more volume was better almost
instantly I bumped pumped out the number
of sets on all my exercises
unfortunately it didn't end up
skyrocketing my gains the way I hoped it
would it wasn't until more research came
out that I realized the mistake I made
you see while this analysis did suggest
that more was better it didn't let us
know just how far we could push it while
still continuing to see better gains
fortunately 6 years later a new group of
researchers decided to perform a similar
analysis this time they compared lower
volumes of less than 12 sets moderate
volumes of 12 to 20 sets
and high volumes of more than 20 sets
per muscle per week they also
standardize the data by only looking at
sets performed within 6 to 20 reps the
result well although moderate and high
volumes led to more growth compared to
low volumes in almost all the muscles
measured there were no significant
differences between the two the one
exception was the triceps which
responded better to higher volumes but
we'll talk more about what this means
later on but overall this analysis
suggests there may be some kind of upper
limit we to much much volume doesn't
lead to more growth and in some cases
might even hinder growth because of
recovery issues The Sweet Spot seems to
be somewhere within the range of 10 to
20 sets per muscle per week but this is
still a very wide range 20 sets is
double the time and work compared to 10
sets to find where exactly within this
range is best for you there's five other
factors you need to consider the first
of which is your individual response so
the studies we covered earlier while
they do provide us with great insight
they look at averages to see what the
best General recommendation is but in
the case of volume it seems to be highly
individual illustrating this is a 2019
study from the Journal of sports science
where they had 19 participants train one
leg with 6 to9 sets per week and their
other leg with 15 sets per week after 8
weeks roughly a third of the
participants had a leg that responded
better from low volume a third had a leg
which responded better from high volumes
and a third had a similar response in
both legs suggesting that what one
person can recover well and grow from
may end up being too much for someone
else now later in this video I'll show
you guys how to determine if what you're
currently doing is too much or too
little for you but one thing that will
play a big role in that is exercise
execution Max UC a 22-year-old natural
bodybuilder experienced this firsthand
it was probably 30 30 to 40 sets per
muscle group per week for example you
know a chest day I was doing every chest
movement I could think of you know upper
chest flies incline bench press flat
bench press all these sets were sloppy
and you know my I wasn't actually taking
the muscles to failure know I tell
myself all right 30 reps of bicep curls
and I'll stop once I hit 30 and then my
last 15 I was I was just swinging up and
down it was a mess I mean eventually I
got to a point where months down the
line I just wasn't seeing any progress
in terms of you know my lips weren't
going up I wasn't putting on any muscle
so now I'm doing anywhere from 7 to 12
sets per week per muscle group as as
opposed to you know 30 plus I've
definitely seen the most growth I've
ever seen in terms of you know raining
quote unquote a lower volume than normal
and you know the the thing that really
helped me do that is you know training
very close to failure because when
you're training very close to failure uh
your muscles just won't need that many
sets but you know when that set gets
hard you need to maintain good form if
your form is breaking down to where you
know you're using momentum and your reps
are getting super sloppy then you know
you're not taking your muscles to
failure so the last thing I did when it
comes to you know lowering my volume
that really helped was taking longer
rest periods because obviously you know
when you're training very hard and very
intensely your muscles just need to
require more rest I think when you
maintain proper technique and you take
your muscles to failure then hair that
with a lower volume approach you're
you're doing everything that you need to
do without going overboard and creating
all of this fatigue and creating all
this muscle damage that needs to be
recovered from this allign with my own
experience as well actually push
yourself close to failure on all your
sets while maintaining good form and
you'll get way more out of less but Max
also mentioned he ended up taking longer
rest periods between a sets which is
another factor that will affect how much
volume you need to grow if you take
shorter rest between sets such as less
than 2 minutes research suggests you'll
need to do more sets to get the same
amount of growth as you would from
taking longer rest and unfortunately the
research I covered earlier that helped
us come up with that 10 to 20 set range
use studies where the rest periods
different some studies use shorter rests
whereas other studies use longer rests
so if you usually take longer rest
periods I personally recommend at least
2 minutes between most of your sets it's
likely that the lower end of this 10 to
20 range will be best whereas the higher
end of this range would likely be
necessary if you mostly use shorter rest
periods but this also depends on the
next Factor how you cter sets so
remember how in the meta analysis we
covered earlier none of the muscles
responded better to really high volume
voles except for the triceps well it's
important to consider how they counted
their SCS generally researchers still
count muscles that are indirectly worked
with an exercise as one full set for
that muscle so for example during the
bench press they'll count that as one
set for the chest and also one set for
the triceps now whether or not this
should truly count as one set for the
secondary muscle is Up For Debate but it
does affect the volume recommendations
for example even though the study showed
that triceps responded really well to 20
plus sets per week if you look at the
average person's workout routine this
would only be about six direct sets for
triceps if you also counted all the
pressing movements they're already doing
now the front side and rear delts as
well as the biceps probably fall under
this category as well unless you want to
prioritize them they don't need quite as
many direct sets because of how often
they're indirectly worked this also
applies for Regions within a muscle the
chest for example doesn't need 10 sets
each for the upper middle and lower
portions
rather the chest in general would
require around 10 weekly sets and you'd
ideally split those sets up by using
exercises that emphasize the different
regions and I also think this
discrepancy in how people count their
sets is why high-intensity training
where you usually do just one step per
exercise can work and has worked for
many people you see in the research we
covered subjects would stop each set
once they reach failure or close enough
to it but Dorian Yates six time Mr
Olympia who is popularized
high-intensity training describes his
set as one all out set extended Beyond
failure with Force reps rest pause reps
or dropsite reps a set is properly
finished only when additional movement
is utterly impossible so as you can
imagine one set performed in this
fashion can very likely be the same time
under tension and stimulus that two to
three normal sets would provide lastly
and probably most importantly not
everyone should be doing what's optimal
although somewhere within the 10 to 20
weekly set range is probably what will
maximize growth you'd be surprised with
just how little volume you need to still
get really great results 10 sets doesn't
give you double the growth as five sets
each additional set you do only gets you
marginally better gains and if we look
back at the 2017 man analysis we covered
earlier even though 10 or more weekly
sets led to the most growth 5 to 9
weekly sets still gave about 80% of the
max growth so for example for chest this
could be as little as three sets of
bench and three sets of flies every week
which could pretty much cut your workout
times in half in fact in some cases even
in trained individuals just three sets
per muscle per week has been shown to
build some muscle so if you're having
trouble just being consistent in the
first place don't chase optimal do what
you can and realize you can still get
great results with far less than you
think and at the end of the video I am
going to provide you guys with a free
minimalist and optimal workout routine
you can use with all the science and the
sets they can care of for you but first
we need to discuss how exactly to start
applying all the research we've covered
first off I'd recommend starting off at
the low end of the 10 to 20 weekly set
range especially if you're a beginner
you don't want to do higher volumes than
your body can currently handle 10 weekly
sets for chest for example could look
like this if you trained all your
muscles twice a week which is generally
how I would recommend splitting your
volume up now even if you're past the
beginner stage dial in your form make
sure you're pushing hard enough take
longer rest periods and it's very likely
you'll start seeing better results
despite doing far less than you were
before but eventually as you get more
experience you may reach a point where
your gains have completely stalled and
your body is actually ready for more
volume but before you make any changes
I'd recommend going through this
flowchart from the muscle and strength
pyramids book written by researcher Eric
CS for example if you're sleeping well
pushing hard with good form and eating
it enough yet you're still not seeing
gains then you might actually need more
volume in this case add about two more
weekly sets especially on muscles that
are lagging behind and see how you
progress otherwise you might actually be
doing more than you can recover from and
might need to take a break or decrease
your weekly volume now since you stuck
around for this long I thought I'd leave
you with a gift I've created three
different weekly workout plans a quick
3-day per week minimalist routine with
around six sets per muscle a 4day per
week routine with 10 sets per muscle to
potentially maximize gains and a 5-day
per week routine with around 14 sets per
muscle for those who might need a little
higher volume they're completely free
and you can grab these routines over at

are looking for a fully customized done
