> The two rules of the gyms are basically : no machines
Machines are fine and useful. Better rule might be "don't only do machines". But even then, I'm pretty sure someone experienced could design a routine that would get them good results with nothing but machines.
They provoke a "backpropagation" of the force you are exercising in the orthognonals of the machine work axis directly into your joints. Risk of injury at heavy weights. doesnt happen with free weights
