Problem #1 with the training of the biceps: Not always it is more the best thing If to make 4 series is better than to make 3 series, Why not simply I make 10 series? And better still, Why not them training all the day? It has been said already before, but obvious it must say again: Less often is more. Especially if you were not equipped with friendly genes with muscles. Your goal in each training with weights simply must be excederte in your last exercise. Once you obtain this with half extra kilo or a few extra repetitions, then the moment arrived for continuing with the following exercise. You do not torture your muscles during another hour as if you were a Nazi. There am shortage that this in a concept difficult to catch for many skinny ones because they are obsessed in the instantaneous allowance to cause that their great biceps see during the exercise and not in how they see when they leave the gymnasium, takes which us to our following problem. Problem #2 with the training of the biceps: To be obsessed more with how they see while you train instead of when you are not training! The problem #2 connects with the problem #1.The certain thing is that it enters more time you train your biceps, even if the weights are not extremely heavy, you can obtain a quite decent pump that can cause that the heads turn around in the gymnasium. This attention and perception of which you are making something beneficial are deceptive. If there is something to say with respect to maintaining the blood in the muscle as much as it is possible; nevertheless, if the exercise takes control of weights that do not overload your muscles and emphasize an increase in the force, your biceps will be deflated quickly to its normal state without there is a true muscular growth.
