What is a pilates reformer and how does it work?

A pilates reformer is a resistance-based exercise machine comprising a sliding carriage, a spring system and a system of pulleys and ropes. As the user pushes or pulls against the carriage, the springs provide adjustable resistance that challenges muscles through a full range of motion. Unlike floor-based Pilates, the reformer allows for greater movement variation, deeper muscle engagement and more precise control, making it effective for rehabilitation, strength, flexibility and posture improvement.
