How to remove shoulder involvement in bicep exercises?

[Creatine]

First of all I am not a curl bro and yes I do work my legs. Only reason I say this is because threads about biceps seem to get flamed sometimes.

My question is whenever I do bicep exercises: dumbbell curl, hammer curl, barbell curl, pretty much any type of curl, my front delts always fatigue before my biceps do and I feel like my biceps don't get adequate work from this.

I keep my shoulder blades retracted, elbows remain in the same position, and have experimented with heavy and light weights but nothing seems to help. The only exercises I can really feel my biceps working in are incline dumbbell curls and sometimes on concentration preacher curls.

Is this just a case of having weak shoulders or is it something else? I was thinking if I incorporate more rear delt work it will help stabilize my front delt because I haven't been doing much direct rear delt work lately.

Any opinions are welcome

Is the fatigue in the deltoid on both sides or your shoulders or just one?

It happens in both of my shoulders but its much more noticable in my right shoulder (dominant side)

You should be doing rear delts every shoulder session in my opinion, there are actually a lot of diffrent rear delt moves you can do so you don't get bored.

Do you lift your upper arm as you curl up? I see a lot of guys do that. Your entire body should be completly stable, and your shoulders should be held back but don't squeeze them super tight or you can strain them that way. Basically you should just be trying to stand with good posture.

I think the bold could be part of the problem. I may be putting more tension on my delts by trying to force them back instead of just keeping my shoulders straight. And I keep my elbows to my sides throughout the whole movement, as far as I know

It's most likely that your humerus' are internally rotated and makes for restricted ROM during certain biceps exercises.

I find less delt activity with drag curls, I may be pulling this out of my ass though so if anyone wants to chime in

and I'm guessing there is nothing I can do to correct this?

I have tried these but still felt it in my delts a lot. I don't know the proper form though, I only went from seeing a quick video of it so I was probably performing the exercise wrong

The opposite actually. An internally rotated humerus is the result of an imbalance in training.

AWESOME link! I did the "flashlight test" and did alright. I could tell beams were starting to come together when I got as far back as I could, though. I'll try what they recommended I the article.

Thanks for all the responses guys

Try curling on a preacher curl attachment and it will isolate your biceps and after getting used to it your arms may adjust.
