Dumbbells Vs. Machines What Is Best in Bodybuilding?

This is a classic debate in the world of fitness. You walk into a gym and whatever your goal (toning, hypertrophy, recovery of injuries…), what you choose: dumbbells or machines?. There is everything, who prefer machines for comfort and those who prefer the weights to have greater control over the movement.

Advocates of machines tend to argue that the muscle does not distinguish if the charge comes from a free weight, such as dumbbells or bar, or a machine designed to work specifically with a muscle. But this is not quite true.

In favor of the dumbbells and weight free:

Machines are still a default movement, and it is true that they will work in a very specific manner a muscle, but cufflinks and other free weights when performing the movement, is continuously produced a feedback process whereby agonist muscles, antogonistas and synergists work together to perform the desired movement.

In short, free weights will entail more muscle fibers and more muscles working with weights. It is not more than the proprioceptive factor, by which the body perceives positions of the segments and continuously corrects the movement. In machines is difernente, you only have to worry about making the move because this is already bounded.

A simple example: When you perform a dumbbell shoulder exercise you must control So where you lower the weight, take care that the movement is correct, control the descent. Throughout this process in addition to intervene the deltoids, Synergist muscles will help to the movement of the exercise so that it is done properly.

On the other hand with a machine the movement is limited and you know that the weight will not go to either side than that of pre-established movement, so you stop working those muscles synergists, including the eccentric phase is neglected because it is known that there is a stop to restart the movement.

Another factor is the nervous. The muscle, which has nervous component, when training sets more neuromuscular connections with muscle fibers as a process of adaptation. As in free weight training muscle solicitation is greater will establish greater connections and therefore a higher-gain strength. Machines these connections will also be established, but requesting fewer muscle fibers will be lower and therefore gain strength also.

In favor of machines:

In the world of sports, nothing is black or white, everything has its term medium and its pros and cons. Why machines also have its positive side and everything will depend on the objectives that we want to achieve.

The machines are very recommended for beginners in musculacion-tonificacion activities already that can go learning easy movement will continue to work the different muscles.

Another point in its favor is the security and stability of the movement. For those who are starting, the lack of force or rookie similar no errors will bring evils greater than a sound topetazo of the machine stops. In experienced people that you need to take much weight also must come first factor security, and machines have it because if the series is up to the depletion and are no colleague who hold the weight, the machine usually always take safety limits to interrupt the movement.

If what is claimed is a muscle work specifically and do not want others to intervene, the machines are perfect for this, to isolate the muscle that is going to work and not let others steal the limelight.

If the goal is to gain muscle mass you should know that the synergic action of the stabilizing muscles is very important to gain volume since these muscles serve as support for the larger muscles that you stand out in volume. It is logical since it would be like a building without foundations, this will not build as much muscle imbalances and avoid muscle and nerve injuries.

Closure:Variety is the spice and you always have to analyze what one intends to choose the appropriate option. However as a fundamental principle of the training is the variability of the practice, it is highly recommended to toggle these two modes of work in the gym, especially if your goal is the work of force in a healthy way. If what you want is performance and grow at the top… that already is a matter of consultation with specialists.
