Are they a vastly inferior way to train, needlessly diverting people from free weights, or do they offer an advantage that makes them a productive addition to a program? While we won’t wade into that debate here, we do admit that when it comes to machines, their greatest asset can also be their most glaring liability— that is, unless you just acknowledge that attribute and maximize it. MACHINE PRECISION That so-called asset and liability? The fact that a machine will often lock you into a fixed range of motion, which in turn lessens the involvement of stabilizer muscles that are otherwise called into action when doing a similar barbell or dumbbell exercise. For instance, when doing a barbell or dumbbell bench press, your pecs take on their fair share of the load, along with your front delts and triceps, but also your lats, core, and even your lower body will tense to brace your body during a rep. With a typical machine press, that’s not the case. Your pecs, delts, and tri’s will still engage, but since the machine’s path is set, you don’t have to worry about balancing the load. “Machines dictate the path of motion in a rep, which may be good for beginners or people who are really looking to isolate a certain muscle group,” Liles explains. “The downside to machines is that they eliminate other areas of the body that could be engaged to develop balance and stability. “Most machines require you to sit, or involve a track that the load moves through,” he continues. “So muscles that help with stabilization— like your legs and core—are sometimes not fully utilized. This can prove detrimental when these movements are FLEXONLINE.COM 79
