The reformer is a flat platform, called the carriage, which rolls back and forth on wheels within the frame. The carriage is attached to one end of the reformer by a set of springs which provide choices of differing levels of resistance as the carriage is pushed or pulled along the frame.
All kinds of pilates exercises are done on the reformer and they promote length, strength, flexibility, and balance. Most Pilates reformer exercises have to do with pushing or pulling the carriage or holding the carriage steady during an exercise as it is pulled on by the springs.
Exercising with the reformer is possible for anyone, at any level of fitness. It’s a great way of learning the basic principles of pilates and is often used in combination with matwork pilates classes
