are you really required to do different exercises to emphasize the different heads?
How to Hit Your Biceps Long Head & Short Head Muscle?
December 05 2009
As shown in the picture, biceps brachii is one set of muscles in your upper arm.
Biceps Brachii consist of two heads: Long head & the Short head
Both these heads can be emphasized differently since the long head is bi-articulate (crosses the 2 joints: shoulder & elbow joint.).
Long Head: The long head (& the short head) can be emphasized with incline dumbbell curls. The nice stretch you feel in your biceps when doing incline curls is in the long head.
Short head: The short head can be emphasized by doing preacher curls. Since the shoulder is flexed (or uuper arm is raised) the long head is de-emphasized.

No. As I wrote both the heads can be emphasized effectively with incline dumbell curls.
When doing regular curls with a barbell or dumbell, you are emphasizing brachaillis, and short head and slightly de-emphasizing the long head.The very reason why people bring their elbows back when doing curls is because that brings in the long head into action and helps to lift the weight.
If you notice, it is easy to keep the shoulders back when doing “alternate” dumbell curls which brings in the long head.

It’s the long head that gives the peak. If you do a back double biceps or look from the side, it is your long head that gives the peak.
Thanks Anoop, I am glad you clarified that for me. I have had it backwards for some time.

You can also emphasize your short and long head by changing the grip width. Wider grip hit your long head and narrow grip hit your short head. It has to do with the stretch at the origin of the muscles. But the shoulder position emphasizes the heads much more than the grip width.
Finally found an article that listed the right information D:. So many people have this completely backwards :].

Interesting article. Ive been doing bicep curls now for 14 years, and still dont have “the peak”. Ive tried everything. I always end up with a bicep impingement when doing heavy curls though.
Sucks being naturally skinny!

The wide grip emphasis the short head since you are stretching that muscle when take a wider grip
in your earlier reply you said that wide grip hits the long head and the most recent one says that wide grip hits your short head? i dont get it
does wide grip hit shorthead or longhead?

Thanks for the comment.
I would say it emphasis the short head or the inside head. Try it and you will feel it there. I got it wrong in the first comment. Thanks for bringing it up.
Can you please explain “But the shoulder position emphasizes the heads much more than the grip width” a little more? In other words, what does one have to do with the shoulder to emphasize the outer head.
You’ve written it all upside-down.
Preachers will hardly target short head, if at all. The short head of biceps is a flexor of the shoulder, and in preacher curls, the stance taken puts shoulder into flexion, and hence the short head of biceps into active insufficiency. hence, long head almost entirely takes over, along with brachialis of course.
On the other hand, incline dumbbells will put short head on emphasis since in incline position, the arm hanging down the bench is in the position of extension, stretching short head of biceps and thus putting it into use. This is not to say that long head will be inactive. It will just not be as active as in preachers.
The grip width is related to rotatory movement of the arm. Essntially, when arm is medially rotated, long head is preferentially used over short head (our arm is slightly medially rotated in close-grip stance) and vice versa.
As with shoulder, whatever the movement, long head is always active, since it arises from supraglenoid tubercle (passing from above the humerus) and has to stabilize shoulder during all resistance flexion movements at elbow. Where it shares any co-activity with the short-head, less stress is put on it though. So I can tell you two positions in which short-head is active (and as a result of which long head is less active). These are:
1. Shoulder externally rotated during flexion (described above)
2. Shoulder extended (extended shoulder stretches the short head of biceps, effectuating stretch-reflex and automatic contraction of the stretched muscle).
Hope it helps!

Thanks for the comment.
Which head helps in shoulder flexion or raising the arm to the front? Short head or long head? Look at the picture of that helps.

The long head crosses the shoulder and elbow joint. When you shoulders are raised like in preacher curls, your long head has already contracted to raise your arm, now it doesn’t have much fibers to do the flexion job. So the short head is recruited. Does that make sense?
I want to point out the basic mistake here. In preachers, the shoulder is NOT raised (not abducted). It is FLEXED. Flexion and Abduction are two different movements. Abduction is when you raise your arm towards your head, i.e cranically. Flexion is when you make arm moves closer to your body. Shoulder flexion is the job of pectoralis major and anterior deltoid, but short head also contributes slightly, as it comes from coracoid process and is closer to shoulder joint than long head. That puts this short head into active insufficiency, and shifts the work load to long head. I agree that if you were to flex your elbow in a raised shoulder (i.e abducted shoulder), some of long head will be used to stabilize shoulder rather than perform elbow flexion, but in preachers, the shoulder is flexed and is very stable. Preachers is almost always a long-head and brachialis exercise, muscles on the lateral aspect of arm, and very much less so of short head.
Secondly, I would also like to point out that even in a raised shoulder, long head DOES contribute to elbow flexion. Shoulder abduction is primarily the job of deltoids, trapeizus and serratus anterior, and if these muscles are strong enough, little of long head is needed for shoulder stability.
We have studied several MRI researches in our anatomy classes (needless to say but I am a medicine student), and most studies have clearly demonstrated the fact that long head is ative in almost ALL flexion movements across elbow joint. Short head is less so. partly because of it’s medial and hind position in the arm, and partly because it has yet another job to do, an even more important one than elbow flexion or shoulder flexion: SHort head of biceps is the strongest supinator of the forearm.
Given so many functions of the short head, it would be a stronger muscle than its brother long head, but then it also would be next to impossible to ever isolate this muscle in exercises completely.

I am not sure what you are saying. Flexion involves raising the arm towards your the front of your head and abduction involves raising the arm towards the side of your head head.What is the mistake here?
And almost all the studies have shown long head of the biceps brachii to be atleast more involved in shoulder flexion. Can you show me studies which shows short head to be more involved in shoulder flexion? I am assuming there are quite a few from what you are saying.
I guess you have not had much anatomical background behind your claims. But that coming from a commonplace man is understandable.
To save our time, please visit: http://en.wikipedia.org/wiki/Biceps_brachii_muscle
here it says: “The short head of the biceps brachii also assists with horizontal adduction (bringing the arm across the body) when the arm is internally (or medially) rotated.”—That is the shoulder position when long head contributes to elbow flexion, and this is what I’ve been telling on in my posts repeatedly.
Still think it’s not enough?
Please visit the most well aclaimed muscular kinesiology website on web:
“The triarticulate biceps brachii muscles, particularly the short head [2 ] enters active insufficiency through the completion of elbow flexion when the shoulders are more flexed (brachialis becomes more active) or through the completion of shoulder flexion when the elbows are more flexed.”
If you intend still to stay deadset and back up your claims behind reference-absent opinion, then you are welcome. Otherwise, not few but many would know the real story otherwise.
Good luck and Farewell!

When did medical schools use wikipedia and exxrx.net as scientific reference? (:-
Let me repeat the question again: Do you have any studies to show that short head is largely involved than long head in shoulder flexion?
I am posting an excerpt from one study for you:
Function of the long head of the biceps at the shoulder: Electromyographic analysis. Andrew S. Levy, MD,a Bryan T. Kelly, MD,b Scott A. Lintner, MD,c Daryl C. Osbahr, BS,d and
Kevin P. Speer, MD,d Summit, NJ, New York, NY, Indianapolis, Ind, and Durham, NC
These 11 electromyographic studies have shown the long head of the biceps to be a shoulder flexor in 7 studies,a shoulder abductor in 3 studies, a shoulder internal rotator in 2 studies, an external rotator in 1 study,a shoulder extensor in 1 study, an anterior stabilizer in 1 study, and an abductor only with resistance in 1 study.2-8,17,24,28,29.
The short head has been rarely studied compared to the long head. There are lot of studies on the biceps long head and it’s functions.
Thanks for the comments.
Debates are always fun, but let’s put this to the practical use.
Which exercise(s) are best for isolating (as much as possible) the long (outer) bicep head?
Close grip db/bb raises
Incline db raises
How would we rank the above, or feel free to add your own suggestion.
i hav a short headed biicep and it is nt very much visble in t shirts…wat can ii do
Dear me, some medical students have real bad attitudes. A good, healthy debate should not have deteriorated by way of such condescending comments being posted by one side.
When did medical schools use wikipedia and exxrx.net as scientific reference? (:- ..........lol ,i liked it
really felling sorry for the fate of patients who is going be get treated by this medical student in future after he becomes a doctor.. lol

May I suggest Gironda Curls as an excellent isolation exercise for brachialis and long head of biceps?
Except of course for who shoulder internal rotation is a problem.
