Trying doing reverse ez bar curls. I have a hell of a pair of biceps with great peaks although I am a powerlifter. Reverse curls will make your forearms bigger and really bring in definition to where the biceps and forearms connect. Also reverse curls wont strain the wrists or elbows really and they will make your arm look a lot wider from the front. If everyone who trains biceps switches from reg to reverse curls for a month, your biceps should grow noticably.
