Workout Your Way To Success

In bodybuilding, the goal is to shock the muscle and then bring him enough nutrients to rebuild and finally let him rest for him to succeed. To succeed in surprising him, one must be attentive to all the details and concentrate on the essentials. But we must also know how to evolve in its way of proceeding and focus on certain aspects often left aside. Repetitions, for example. Have you ever wondered what really happens when you make one? No? All the better because that’s what this article will tell you about. When you know it, you should be able to apply your new knowledge to your practice, and therefore better progress.

Explanation of a repetition

At the most basic level, a repetition of upper body exercises breaks down into 3 phases: the concentric contraction, that is to say the action of lifting the load, the transition stage, and the eccentric contraction, when you lower the load.

Generally, your movement starts with the concentric contraction, but it is not the case all the time. Squat and bench press are exercises where you start by lowering the load before lifting it.

If the two main phases are called contraction, it’s not for nothing. One might think that the muscle relaxes during the eccentric stage, but that’s wrong. In both cases, the muscle is contracted. The difference is that it shortens during the concentric phase and, conversely, it stretches during the eccentric phase.

At the physiological level now, during a repetition, the contraction occurs through a nerve impulse, a kind of message transmitted by the brain to the muscle, through the nerves. It is the muscle fibers that contract. But they do not necessarily do it all at the same time. You have to reach a maximum contraction for all these fibers to work together.

The first phase: concentric contraction

During this phase, the muscle is shortened, as we saw above. In doing so, he pulls on the bones and joints to which he is attached; he tries to bring them closer to each other. If you perform a curl bar, for example, you will observe your forearm and your arm that is close to each other by ab exercises.
