In a gym or health club, the adjustable cable machine is often one of the most underutilized pieces of equipment, and when it is used, it is not to the best of its ability. A two-arm resistance band allows for a number of cable machine-type exercises to be performed anywhere you can identify a secure anchor point for the band. The benefit of using either a two-arm resistance band or cable machine is that you can perform pushing, or rotating movements from a standing position, which will engage most of the muscles responsible for controlling both stability and mobility. These exercises can be some of the most effective movements for developing the core strength that can help you to enjoy all of your favorite activities.
