Is it possible for forearm involvement to decrease bicep involvement in bicep curls?

[iso123123]

My forearms are getting huge but my biceps are lagging a bit,
I do feel a huge burn in my forearms when doing bicep curls..

Is it possible that my form is prioritizing forearm involvement over biceps? Can forearms "do the work" in bicep curls? My common sense says that they can only lift it a couple of inches while the biceps will always have to do most of the work anyway... do forearms only work as stabilizers, so whether I lower their involvement or not, my biceps are doing the same amount of work?

you probably aren't doing the curls right. If you have the tendency to curl your wrists it will work the forearms more. Keep your wrists neutral/slightly bent backwards. Also people have the tendency to move their elbows through space and swing with their elbows and shoulders. This also takes away from actually isolating the bicep. Don't swing the weight with your elbows and shoulders and keep your elbows in the same position in the concentric/eccentric. If you still aren't feeling it use dumbbells on a preacher or something.

Use the seated preacher machine. When you put your hands on the handles to grip them, DON'T. Just raise the weight with open palms. It will greatly decrease the forearm involvement.

Sometimes I slack on bicep training, but when I want to bring them back up, this and is my go to movement

no. forearm is for gripping.

Seated Preacher Curls. Even the machine. The machine allows you to not even squeeze the bar. You can use flat hands on them because it is a fixed position.
