- Abstract
Introduction: The Smith Machine has been a popular alternative to free bar exercises because of perceived safety advantages. With the advent of the Jones Machine/MaxRack, it is still a viable alternative to free weight training? Does the Jones Machine/MaxRack have a better combination of free weight results combined with enhanced safety?. History: The Smith Machine, with a fixed vertical motion, was pioneered in the late 1930s, and was adopted in response to increased interest in resistance training, while the Jones Machine/MaxRack were invented in combination to the path options of a free bar combined with safety consideration. Bar Path Comparison: The bench press, deadlift and power clean are exercises that do not have a completely linear path. The squat, in performance, is ideally linear, yet not in learning the exercise. The Smith Machine does not allow the bar path used in major free weight exercises. Strength Testing: Because of inherent friction and bar path limitations, the use of a Smith Machine in testing for free weight-based strength gains is not valid. Conclusions: The Smith Machine does not match the free bar path of the major exercises, while the Jones Machine/MaxRack allow exercise specific and individual bar path variations and matching.
