Biceps Workout Concentration Curls for Big Arms with Victor Costa Vic’s Natural http://www.vicsnatural.com http://www.facebook.com/vicsnatural Concentration curls are excellent for size and shape of the biceps. However, don’t miss the sweet spot of the exercise. A lot of people have a tendency to jerk back or use momentum to get the weights going from the extended position, however, if you are doing this, you are missing the sweet spot of the exercise. Instead of jerking back, start leaning back at the beginning of the exercise, this will extend the arm and let gravity pull the weight downward. This extension will get the weight to “sit” in the biceps. Then, with a relaxed hand start pulling upward. This feeling is awesome. This will help your arms grow and help the biceps directly. Happy biceps training. Please visit my website http://www.vicsnatural.com for my workout dvds and audios. Peace, Health and Happiness, Vic
