Back Extension Machines

Back extension machines are designed to strengthen the lower back, glutes, and core muscles that support the spine. By guiding the body through a controlled range of motion, they help improve posture, reduce the risk of lower back strain, and support everyday movements such as lifting and bending. Suitable for beginners and advanced users alike, back extension machines are an effective way to build spinal stability safely and progressively.
