The use of machines or halteras for exercises for bodybuilding or bodybuilding is a choice which sometimes involved factors beyond the purely technical or physiological, related to psychology, aesthetics or fashions. Veteran athletes in the use of one or another system tend to justify their use and tend to reject change.

I’m going to expose a number of reasons I think that they are objective, so that those who have not is still, opted to have more theoretical arguments. Controversy exists and I am not going to solve it with this post, but I hope to provide a more technical basis.

In general, the free can is richer in minimum varieties of movement (such as rotations or small differences in each replicate travel) and the machine is more analytical requesting greater primary muscles of movement. In the specific case of the squat, these ideas can differentiate the use of the weight free or “multipower”.

The squat free weight is complete in the sense of apply for the activation of muscle chains, and not only muscle groups. This activation is more natural and creates a more homogeneous body power.
The “multipower” offers a fixed route for the movement which limits the variety of the same but, on the other hand, offers a containment to imbalances and sudden loss of control of the bar (for sickness, injury or fatigue) that offers greater guarantees of security.
The squat free weight, by offering more freedom of movement, also requires a better technique. On the other hand, it offers a greater visual control of the balanced of the two hemicuerpos contribution (because the bar does not go up horizontally).
The “multipower” in the purely practical field, facilitates the activity without the help DC other companions.

In my opinion, it is better to make the exercises for free in general, but nothing happens if alternating with the use of the apparatus. Behind appliances there is a commercial interest, both by sellers as for gyms, which “industrialized” bodybuilding (longer more serves more people in less space and less time). But don’t have to be obsessive: diversity is the balance.

As anecdote I will tell you that when he trained in Judo we did squat in pairs, first you missed on her shoulders to mate and then backward. Everything there is.
