Is there any isolation lifts that succsefully hit the outer part of the bicep muscle more so than the inner. Like my front double bicep shot is a strong point, but in a read double bicep shot it isnt nearly as impressive. the muscle kind of grows inward. I know thats problaly genitcally dispostioned but I know doing bb curls with a ez bar hits the inner bicep more. I have always done those, and now have switched to straight bar. Any other movements to bring that side up the bicep up.
