Simple Training Technique for Bigger Biceps-2

Competitive bodybuilders learn to “pose,” or contract, their muscles to maximize their appearance and look as big as all get-out. When bodybuilders pose their biceps, ever notice how the palm is rotated toward the forearm, and the thumb is either tucked inside the fingers or across the middle digit of the fist? There’s good science behind this quirk. The rotation generates a full contraction, thus maximizing the “peak” appearance of the biceps.Using this grip while curling will produce surprising results. Simply position your grip on the bar so the bar rests closer to the butt of your hand, and rotate your knuckles upward. This position must be maintained throughout the range of motion.With your wrists locked, pin your elbows to your sides, forcefully grip the bar and curl upward. At the bottom of the movement, keep the knuckles rotated upward.

Keeping your wrists rolled toward the body throughout each rep will max out biceps growth, compared to reps done without continuous contractions of the forearms.
Adopting this grip into your curling regimen will do two things: It will force you to totally isolate the biceps, and also force you to utilize the oft-overlooked brachialis, the muscle that runs in between the biceps and triceps. Developing the brachialis will push the biceps and triceps apart, creating a bigger arm.
