The Smith Machine has been one of the biggest mistakes in strength
training equipment, in my opinion. This may sound like an extreme comment to
make considering almost every gym and even some rehabilitation facilities now
have them for their people to use. Please let me elaborate before you stop
reading.
My biggest problem with the Smith Machine is that people are convinced
they are still doing free weight movements when they perform exercises on the
Smith Machine. Because an Olympic bar is attatched to the machine does not make
this a free weight piece. The reason is this piece only allows movement in a
fixed plane of motion. This is one of the many disadvantages of machines that
Coach Snideman has stated in his article,
Free Weights vs. Machines.
In any movement that a human performs, almost never are the same
muscles or patterns of movement replicated. This is obviously not new to machine
training, but with the Smith Machine this becomes even more complicated. A
squatting movement is rather complex, especially considering the variations that
are available. Even though the bar does not look as though it moves but up and
down, all the joints are revolving and this simple movement is not simple. The
Smith Machine locks into a very unnatural movement pattern which has the
potential to stress inappropriate structures and not train the body in various
planes.
