@robmen1402 Год назад

People do tend to go overboard with their iso exercies tho. I see it in the gym all the time, they gravitate more towards doing a lot of iso and nearly enough compound.

Man, the Sport Science research is just becoming a meme at this point. We need a Ioannidis (2004) for this field, we aren`t moving anywhere with 0 reliable study replicability and with literal data fraud happening. Studies contradicting each other for like 20 years already.

@HouseofHypertrophy 2 года назад

I feel you. Though I don't think it's all doom and gloom either, there's some great research on many areas (rep ranges, range of motion, frequency). More studies are always better though, and hopefully well designed ones haha.

@ryanrocks7179 2 года назад

I think the issue isn't just in sport science research being published, but research publishing overall. With the demand for publishing increase it leads to a decrease in the quality being published. Research publishing in my personal opinion has become more quantity over quality.

Excellent discussion of study limitations and the fact that some cross multiple joints resulting in not being worked during compound lifts, although compounds do a decent job overall. This is a good example of using research as a baseline for objective evidence (within limitations) as well not ignoring years of subjective anecdotal evidence from real world experience among 10s of thousands in the gym. Good job.

@HouseofHypertrophy 2 года назад

Thank you! I do plan to make an "ultimate guide to ab hypertrophy" at some point. I will say though that it's almost certain training abs specifically is needed to max it's growth. We know taking a muscle close to failure is needed to experience optimal gains (as it maximizes tension on the muscle), and for the abs, the only way to achieve this is to train them isolated. Still, you can experience respectable ab development with only compound movements, but I don't believe it will max its development :)

@HouseofHypertrophy 2 года назад

I can't be certain as I'm not aware of any quality data here, but I'd say for general health, adding many isolation exercises is not needed. Perhaps some things like face pulls could be useful for general shoulder health though.

@siddharthraychaudhuri7250 Год назад

Same here.

@johnk6757 Год назад

I have done that for years, one of Mike Isrataels videos made me question the logic as he says high SFR (stimulus to fatigue ratio, like isolation) movements should happen before low SFR (big compound lifts) movements so the systemic fatigue doesn't impact your performance as much.

@sirvaant 2 года назад

I've ditched my isolation exercises except for calves and leg curls for hamstrings, just experimenting right now, reason being is because I train Hit style with a slower cadence and really focusing on the negative, and what I'm noticing is for instance my forearms and biceps on pull downs get externally worked

@robmen1402 Год назад

I also train like you do, so what I do is I do only 1 iso for the triceps and biceps for example to positive failure also using a slow cadence on the eccentric (5 seconds). That's it.

@TypicallyUniqueOfficial 2 года назад

I think you can build the same amount of muscle either way but at the cost of recovery with compounds (if you want a bigger chest, doing the requisite volume while performing a bench press will also impact all the other muscles involved) and for isolations cost you more time (bench press works triceps, shoulders, and chest all at once wheras doing aa separate exercise for each for the requisite volume is too long). I hurt my back and had to stop doing squats, and I was afraid I would going to lost leg size. I switched to sissy squat machine and even though I was using far less weight I was able to actually build my quads bigger. Takeaway is both of them build muscle to the same degree with different limitations (recovery vs time).

@HouseofHypertrophy 2 года назад

Interesting, thank you for sharing! Though I think it's worth pointing out in many cases compound and isolation are complementary, as alluded to in the video, they may cause slighly different regional hypertrophy :)

@vrnvorona 2 года назад

I think it's commonly known that squat machines or even simple leg press *will* increase size, however may not translate to better squat performance. And a lot of very built bodybuilders don't do squats - their target weight is so absurd that without isolation it's too dangerous to even try.

@KurokamiNajimi Год назад

@@vrnvorona “And a lot of very built bodybuilders don’t do squats” Yeah you mean ppl blasting PEDs and or great genetics. You don’t have to do any specific exercise to grow but pause squats to depth or ass to grass are the most stimulating quad exercise. That’s why when you compare the weight on leg press it’s much higher than squats, squats are harder

@KurokamiNajimi Год назад

No the more advanced you become the more hard sets you need towards a muscle. This is why many are torso dominant with relatively small biceps, triceps, and forearms arms. They don’t do enough arm isolation. Rear delts, calves, and glutes tend to be another weak link. Bench doesn’t stimulate the shoulders or triceps as much as isolation exercises or the OHP in the case of delts. Think of benching as a half set to your front delt and half to triceps (unless you do heavy 5x5 close grip benching then you can count it as a full set to medial head). Pull ups are a half set to your biceps. It’s like saying only do squats and leg press for lower body

@thatweakpowerlifter2515 2 года назад

If you diedicate a day for isolation exercise it will grow, trust me , my arms grew way too fast I got stretch marks on my biceps and triceps

@justinw1765 Год назад

It just kind of makes intuitive sense to me that a combination of mostly compound with some key isolation exercises, seemed more efficient. Some people might laugh at this, but I am using a combo of a sliding bench trainer with some free weights and some calisthenics. The sliding bench trainer and calisthenics are primarily compound (though they don't necessarily *have* to be, just the way I'm mostly using them) while the free weights are a mix but with an emphasis on isolation overall (in this case). P.S., I like this current system a lot because of a few key reasons not related to hypertrophy: 1. Going to a public gym takes up more time. 2. I'm an introvert and don't particularly like being at a gym. 3. I'm saving cost over long term since I'm not paying for a membership. 4. This system is low cost (the S.B.T. for example, was under a couple hundred new) and doesn't take up a lot of space all in all. 5. I can use the S.B.T. as a bench for things like dumbbell bench press (though a bit inclined).

@Dane33602 Год назад

I'd like to know the experience levels of the people tested in these studies. If they were beginners, I'm not surprised that lat pulldowns alone did as much as lat pulldowns with curls for biceps growth, as any stimuli to an untrained muscle will work. Adding curls isn't necessary. But I find it difficult to believe that the same results apply to an intermediate or advanced lifter. From personal experience, last year I suffered an elbow injury that prevented me from being able to do any kind of curl other than light partials on a machine. But I was able to do rows and lat pulldowns as usual. After 2 months of partial curls, but still training my back as usual, my arms slowly atrophied. Exercise performance matters too, especially with something like lat pulldowns. Most people I see doing lat pulldowns aren't engaging their lats properly. It probably is more of a biceps exercise than it is a back exercise for them. I'm trying to take my biceps out of the exercise as much as possible. Same with bench presses and triceps. I'm trying to engage my pecs, not my triceps, and the pecs are where I feel it most. If your triceps are lit up after bench pressing, something isn't right.

@despairingleonardo 2 года назад

I hate doing workout so I minimise to do only 4 isolation exercises for my desired look, which are Biceps & Hammer Curl, lateral raise, chest fly and single leg lunges. and i only do 1 type of workout a day.

@@HouseofHypertrophy u are right. I only do dumbell at home so there are some limitations. A month ago I was doing compound exercises, including back exercise, for months but I found that the progession was insignificant and I hit plateau because I already lift the heaviest dumbell. Now I switch to isolation exercise i feel more stimulation to the muscles i want. I dont need a perfect look so some biceps and pecs are enough. haha.

@ScytherOnSpree Год назад

Awesome breakdown as always, although not to be pedantic but there is one contradiction in the video (probably by mistake): At 9:50 it talks about how triceps long head is shortened unless stretched overhead, yet 10:20 brings up triceps pushdown as example of an isolation exercise for the long head. It's funnier if you remember the video about overhead extensions being superior for triceps growth for this very reason exactly :)

@HouseofHypertrophy Год назад

So this video was done before that study came out haha :) - but it's still worth noting pushdowns do grow the long head well still, just not as well as overhead extensions

@HouseofHypertrophy 2 года назад

@davincibz1 Год назад

Yes, the video was interesting. To conclude, the more type of exercises you do from different angles, the more growth. You can't say a squat will grow the legs just as any other exercises combined, because it hits only parts of the muscle. I bet that in the future, they will look back at us and say: lol, they only did squat, leg press, hamcurls and extensions for the legs. They did not use our 4D 360 antigravity multiangle pressing system.

@bora5921 Год назад

What about the question if isolation exercises combined with, for example bench press makes you stronger in bench press compared to benching only?

@HouseofHypertrophy Год назад

Interesting question. I think it depends, if an isolation exericse is used to bring up a limiting muscle in bench press performance, then I think it could help. Moreover, muscle growth in the long-term likely contributes to strength, so this is another route by which isolation exericses may help bench press performance (the difference would probably not be readily seeable in the short term, but probably is the very long term)

@HouseofHypertrophy 2 года назад

They used EMG, something which is very very limited. I described a few of the points as to why this is the case in a video titled "How to Change Muscle Activation With Any Compound Exercise (Maybe)" at the 4:55 time point :)

@thatweakpowerlifter2515 2 года назад

Well, more activation in EMG doesn't necessarily mean more growth. But OHP is a good exercise for side delts in general. Unlike other compound exercises, I believe you can not be strong at OHP without having significantly large delts.

@HouseofHypertrophy 2 года назад

As detailed in the video, lateral deltoids, calfs, hamstrings, triceps, biceps, and the quadriceps (rectus femoris), likely all need isolation exercises to max overall growth. I'm not sure about the check or back as there's not much research here, but compound exercises may very well be perfectly fine for these muscles.

Isolation exercises as a beginner feels like a waste of time and energy.

I think that depends what you're doing your isolations for. Isolation exercises are good for establishing mind muscle connection. I always had trouble with DB OHP being week and feeling uncomfortable until I did a lot of lateral raises, then all of a sudden my OHP felt great and my shoulder development improved significantly. I currently still have huge problems with glute activation for my deadlifts.

@KingAdjust Месяц назад

I did isolations for my first year of training and gained no muscle all I got was a little definition and nothing else, french presses, reverse curls, curls this was also when I was a newbie and yes I went to failure on them too, then I switched to compound movements heavy row's, bench press, OHP, etc. and saw results in less than 3 months in my triceps, biceps, forearms, and of course the other muscles that these movements work it would actually be a huge waste of time to do isolations in your first year of training, I and many other's are proof of this it's just fluff and pump until you're advanced where you can move a decent amount of weight on isolations to get that extra 5-10% of muscle growth, and definition but even that isn't necessary unless you're a bodybuilder going on stage most muscle definition is about cutting off fat anyway

@OwGash Год назад

I cant imagine anyone saying isolation is useless. Just dont overdo it when also doing compound. Isolation is still great to make up for weaknesses/you can do em on offdays I also do it when my shoulder is injured cause a lot of compound=shoulder movement edit: nvm, finished the video, this was all said xd

@robmen1402 Год назад

No, you should not overdo it when doing iso, you have it the other way around. Focus more on compound and do less iso but do iso. For example if you do a push or chest day, a couple sets of iso movements for the triceps should be more than enough on that day. The majority of your time and energy would be better spent focusing more on the compound. Better pay off overall.

@ianwilson4841 8 месяцев назад

The biomechanics are pretty clear. When performing a multijoint movement the prime mover will perform the bulk of the work. So if you want to maximise hypertrophy and strength in a bicep or tricep muscle, performing an exercise where those muscles are the prime mover. There's plenty of anecdotal evidence where people claim compound exercises worked better for them then isolation movements, and vice versa. As with everything when it comes to exercise, the best piece of equipment you can use is a note pad and pen.

@nicksenseitv4922 Год назад

If ita true the only muscle need to isolate is the Long head tricep. Damn thats very hard to grow without Skull crusher.

@NBDYSPCL 2 года назад

Seems to be entirely volume and resistance dependent. If you are going hell-for-leather on compounds, you likely dont need isolation exercises. But if you are going easier on compounds, you can ptobably bang out a few curls at the end. If you're focused on performance or aesthetics, then isolations are useful to you. Otherwise just stick mainly to compounds.

@HouseofHypertrophy 2 года назад

Depends on goals. As detailed in the video, many regions and muscle groups are likely suboptimally trained with compound movements only :)

3:14 Alright somebody please explain how the difference is not significant here? That is literally more than double the growth. In my mind the only way to get away with calling it "not significant" is to say that the growth overall was too low. But then we can throw out excercising entirely because they did 30-42 fucking sets. In fact it wouldn't surprise me if there was no difference because even at the lower end of 30 that's like twice the sets you realistically need

@HouseofHypertrophy 2 года назад

Train them well and be patient, haha. I'm not sure what else. So long as you're progressing your chest and shoulder exercises over the long-term, all should be well.

For my shoulders I found my issue was a lack of mind muscle connection. A long time doing lateral raises with a lot of sessions focused on slow focused movement, slowly building volume (with Arnold presses) finally got my shoulders to engage properly. For rear delts I just did Jeff Cavaliers' high row. Though I'm still pretty small so I dunno if you wanna listen to me.

Yeah, some science isn't really scientific, haha. Science done well is great though :)

Common sense isn't that common and what people think of as 'logic' isn't that logical. Science just isn't done that well a lot of the time, and a studies findings can only be narrowly interpreted. That's why they do meta analysis - to more broadly apply scientific findings, and even then.

The only isolation you need is an overhead extension exercise for The long head of the triceps compound movements build the most muscle 😎👍

I dont think you thought htis one through well enough. Look at the graphs again, adding even a few single joint exercises increased the results in both cases early in the video. Calling the increases 'not statistically significant' is an incorrect analysis by the researchers because of the short time spans of the studies. Do any of us trained lifters really believe you are going to see a huge difference in 10 weeks by adding two extra sets? NO! You expect to see small steady increases and thats just what the studies showed...if you went for a year at these rates you could call the differences 'statistically significant' and see greater gains I think. But not just in 10 weeks! Take the charts and multiply the results by 10 to get a 1 year result and what do you see? Extrapolated huge significant gains. I dont know that this would happen exactly like that but much of that would I think. I think you need to do some more critical thinking what do you think? I have seen some really smart thinking from you on several of your videos which are btw some of the best out there, keep up the good work!

@shraka Год назад

You'd be thrown out of a statistics class for suggesting multiplying the results by 10 - your margin of error would just increase as you're not adding more data. The margin of error is there to show that the study cannot establish that the difference wasn't just random chance - it could just be noise. You need a longer study with more participants to drown the noise out with quality signal, but you can't just extrapolate that from a shorter study because that's just making things up. More actual data is needed.

Can't be. I curl 60lb dumbbells(perfect form) and rep out with 90lbs on weighted pull ups. I was wondering why the bigger muscular guy was hauling ass with half the weight with dbs curling. So then i tried internal cues and after 3 months my biceps STARTED TO GROW LIKE WTF HOLY TSHITTT!!!! Fuck science well at least most of it. I made the mistake of relying too much on it and not considering the experience of others.
