Pilates reformers are the most popular piece of equipment used in Pilates and are tremendously beneficial in increasing strength, flexibility and balance. Reformers are used by pushing and pulling a platform against a spring resistance in a seated, standing, or upside-down position while controlling the movement backwards or holding it in place. With the infinite ability to adapt, Pilates reformers continuously provide a new challenge for any experience level.

Underneath your reformer’s carriage are an assortment of springs that attach into a metal bar. Just as each of our bodies have their own unique characteristics, each reformer spring has its own distinctive attributes that vary depending on the manufacturer of the reformer you are using. The springs allow you to increase or decrease resistance from light, medium, or heavy as you move through your workout.

To determine spring resistance, you will first want to see if your reformer’s springs are color coded. This will help you determine which springs are heavy, medium, and light. Since the function of springs varies between manufacturers, identical colored springs may represent a different resistance on each reformer. Reformers without color-coded springs have equal tension across all springs. 

Another variation is the number of springs your reformer has. Some reformers will have five springs while others have four. Knowing the total number of springs and their placement within the gear can make a difference in feel and performance. Ask your instructor if you need assistance in choosing appropriate springs for you. If you choose to change springs on your own, always add before you remove.
