I think that's also the case in most natural bodybuilders, judging by the development of their hands. Natural athlete is very difficult to develop Racialists (the same applies to the upper parts of the chest muscles and rear deltoids). Unless you are genetically gifted, the increase of the muscle appeared difficult, largely due to differences in the levels of innervation of different people. Moreover, the left and right load Racialists reacts differently. For example, Introduction to Kyle Leon my right Racialists perfectly responds to the spider flex ion, and left to be desired reduction should be closer to the head. When I look at the hands of professionals, we understand that with such a problem facing not just me. Many of them Racialists developed differently, as is evident in the attitude of "double biceps from behind." However, many mistakenly believe that the imbalance is caused uneven development of the biceps.
Important Points - The imbalance in the development of the biceps and Racialists can cause pain in the elbow, which will limit the movement in working through the biceps. When training back Racialists also gets a portion of the load. Strengthened it, you will become stronger in the exercises for the back, and, consequently, improve it after several specialized training Racialists my results in the exercises for the back considerably increased. I noticed this because of soreness Racialists that appeared after spinal training. Apparently, I learned how to engage in the work of these muscles.
