Back extension machines—sometimes called hyperextension benches, Roman chairs, or glute ham developers—primarily target your lower back, glutes, and hamstrings. When used correctly, they can help you build strength and improve your range of motion. Corey Lewis, CPT, co-founder of 1AND1, says strengthening your erector spinae (muscles and tendons that run from the base of the skull to the back of the pelvis) can help relieve lower back pain, improve posture, and provide greater core support.
High-quality back extension machines are durable and adjustable, with thick padding and handles that make them easy to use.
