When your elbows are positioned ahead of you, such as during preacher curls or incline curls, it tends to emphasize the short head of the biceps. This positioning places the shoulder joint in a more extended position, which puts more stretch on the short head of the biceps, thus emphasizing its activation. Conversely, when your elbows are positioned behind you, such as during incline dumbbell curls or overhead cable curls, it tends to emphasize the long head of the biceps. This positioning allows for greater activation of the long head due to increased shoulder flexion and less stretch on the short head. Ultimately, the different positioning of the elbows alters the biomechanics of the exercise, leading to varying degrees of activation in the different heads of the biceps.

@@MarcoFitser It's still wrong to call it isolation. Let's say your triceps are the limiting factor on a close grip bench press. You're still not isolating anything. Here it's even more ridiculous because the muscles cross the same joints and will both be worked fine in any exercise where your flexing the elbow under load. I doubt emphasizing either head makes that much of a difference.
In that case, “isolation” of a single muscle doesn’t exist as it is impossible to train only 1 muscle, as there will always be some supporting muscles within every exercise. My interpretation of “isolation” is exerting the maximum mechanical load on a certain muscle so that that muscle reaches failure first. When you’re doing regular curls (elbows at the side of your body), you will reach failure eventually with your biceps. But which muscle reached failure first? The long head or the short head? The answer is the weakest muscle will reach failure first. So how can we strengthen and grow the strong muscle if we can’t push it to failure? In that case we can “isolate” that muscle by putting it in a position in which it will reach failure faster than the muscle that is put under less bio-mechanical stress. So when you have your elbows in-front of you, the short head will experience the most bio-mechanical load, your long head will also experience some load, but not to the same extent as the short head. The same is applicable for “isolating” the long head.
Isolating makes no sense. Firstly when you are training both heads at the same time, you will achieve failure at the same time. Secondly you can’t FULLY isolate them at all, so just train them at the same time.
In order to balance out the development of the two heads of the biceps, it is important to include exercises that specifically isolate the short head, rather than both of them. You’re likely to reach failure with one or the other when doing conventional curls, but not both as these muscles have different strength levels. Try doing the same weight with preacher curls as you’re doing with the incline dumbell curls. There will be one that is stronger than the other.
Only reason a muscle isnt growing: ur not training hard enough. This is nit-picking for that extra 1%, get the basics down first. Also you cant isolate 1 of the heads, you can only slightly emphasize them.
@@MarcoFitser True, but imo every educational video should have a disclaimer at the end saying that everything said before it didnt matter if you are not training hard. There are way too many people (i used to be one of them) that care too much about optimal training but don't train hard
I am 100% with you on that. Most people don’t push even near failure, which is the most important aspect to consider for muscle growth. Thank you for your feedback, I will definitely keep that in mind for my next videos!
Normal curls are sure to result in some great gains! Though isolation definitely has more net positive effects on the individual heads. Definitely worth the try💪🏼

No you don't isolate the individual heads because they're both involved in all elbow flexion

If you want biceps train your legs first💪
Don’t skip leg day: because your quads should be the only thing jiggling on you at the beach.
huge hunk
Thank you King💪🏼
I'll try this next time!!!
Enjoy the gains💪🏼

I agree! Still, no harm done in optimizing your workouts from the start. You’d definitely see more growth that way.

This is why your biceps arent growing..
THIS is why your biceps aren’t GROWING
what is the muscel called in the lower half of ur arm
Its called brachialis and dont get it mistaken with brachioradialis. Good exercise are for example cross hammer curls
bruh doesnt fucking matter ur bicep wont look any diff emphasising short or long head itll just get bigger
Normal curls are sure to result in some great gains! Though isolation definitely has more net positive effects on the individual heads. Definitely worth the try💪🏼
