The Disadvantages of Cable Machines

Cable machines are pieces of resistance-training equipment that can be found in nearly all workout facilities. When used correctly, they can be effective for increasing muscular tone and endurance. Despite their numerous benefits, it is important to remember that there are also certain disadvantages associated with the use of cable machines. Limited "form" guidelines, weight restrictions, poor engagement of core muscles, and a lack of safety support can make the use of this type of machinery less than ideal.

  1. Limited "form" guidelines

    • According to the American College of Sports Medicine, the limited "form" guidelines provided by most cable machines is one of their most significant disadvantages. As opposed to lever-style resistance training equipment -- on which exercisers can only perform an exercise in one specific manner -- cable machines can be used in an extensive number of ways. While this does provide numerous options to the experienced weight lifter, beginners may not have mastered the form of the exercises they wish to perform. Instead, beginning exercisers may use dangerous technique or complete the exercise incorrectly, possibly resulting in injury.

    Weight Level Restrictions

    • When it comes to lifting weights, a few pounds can make the difference between a challenging exercise, and one that is impossible. While the use of dumbbells allows exercisers to change the difficulty of certain exercises by as little as one pound, this option is not always available on cable machines. In fact, the American Council on Exercise states that most cable machines generally are set up in a way that only allows for weight increases or decreases of 10 pounds. Limiting resistances to 10-pound intervals can be a struggle for those just starting out.

    Poor Engagement of Core Muscles

    • Even when working on the muscles of their upper or lower body, many experienced weight lifters choose exercises that focus on core engagement. While engaging the muscles of the core is often a no-brainer when using dumbbells, barbells or other free weights, the American College of Sports Medicine reports that it can be more difficult with cable machines. Standing on an unstable surface -- such as that provided by a Bosu ball-- can be effective when it comes to engaging core muscles on a cable machine. Rotating the arms of the machine may also produce some improvements in core muscle engagement.

    Lack of Safety Support

    • Unlike traditional lever-style resistance equipment, there is often limited safety support when it comes to the use of cable machines. Lever-style resistance training is set up in a way that significantly limits the risk of injury -- and while there are no "built-in" safety features for more dumbbells, spotters can always provide assistance. Unfortunately, spotting a fellow exerciser on a cable machine can be difficult, as one side of the body will always be blocked by the resistance machine in question. Making smart choices in regards to the amount of weight used and exercise performed is, therefore, even more important on this equipment.
