bicep peaks?
 

I am new to this, but I am in need of some help. I have been working out for almost 4 years now, and while I have a decent peak in my right bicep, I have almost none in my left bicep. In terms of strength, my left is at times stronger, yet it does not look nearly as big. What is the problem and how can I fix it?

Hi.

I think the best thing you can do is fully flex the muscle at the top of the movement.

Try doing single arm bicep exercises using dumbbells, and fully engage the muscle at the top of the movement by flexing the muscle and forcing them to peak more.

Try working the arms individually, and concentrate on stimulating the muscle fiber as much as possible.

If this doesn't work, I don't know what will.

The shape of your biceps, including the peak, is determined by your genetics, not your choice in exercises. You can't influence whereabouts muscle is added to the bicep, only if muscle is added in the first place.

Isolate the muscle instead of using BB;s

and yes it boils down to genetics as well

its the common situation faced by many users of dumbles as their right side biceps take nice shape but left side dosent takes good shape the solution for this is use heavier dumbles on left side and light weight on right hand side

I don't know if I would ever recommend using unbalanced loads (except possibly in injury cases). I think this is a recipe for disaster. The barbell lifts are your key lifts and you don't want to create an imbalance in your body such that you can't do them properly.

Definitely don't listen to Daniell, like iron said... it's a recipe for disaster.

Sorry but most likely those are just the cards you are dealt with. My right chest has no where near the definition of my left but I'm just as strong with both sides.
