Reformer Pilates is a type of Pilates exercise that utilises a specialised piece of equipment called a reformer. The reformer consists of a flat platform, known as the carriage, which moves back and forth along a frame. It is equipped with springs, ropes, and pulleys that provide varying levels of resistance and support. The apparatus allows for a wide range of exercises that can be performed in different positions, such as lying down, sitting, standing, and even upside down.
