Smith Machine, Commercial Smith Machines

The Smith machine is a very common item of equipment used in weight training. It consists of a barbell that is constrained to move only vertically upwards and downwards on steel guides. It often includes a weight rack in the base to help stabilise it. Behind each runner is a series of slots on which the barbell can be hooked.

Unlike an ordinary barbell, the Smith machine need not be re-racked after a set of repetitions: it can be secured at any point. This is what makes smith machines the preffered choice for many gym goers, because they are safer.  However, the Smith machine constrains the body to a single plane of motion, which produces unusual strain on the body and is not as effective as developing functional strength. For these reasons a regular barbell with a power cage may be preferred. The Smith machine can be used for any barbell exercise in which the barbell moves vertically up and down, such as the squat or the bench press. It is not suitable for exercises in which the barbell moves in an arc, such as the biceps curl or the clean and jerk.
