What is the function of the "Spring" system in Reformer Pilates?

The function of the "Spring" system in Reformer Pilates is to provide variable resistance and support for various exercises. This system consists of a series of springs that can be attached at different tensions to accommodate the user's strength and the nature of the exercise being performed. By adjusting the spring tension, practitioners can either increase or decrease resistance, which allows for a wide range of exercises that can be tailored to individual fitness levels and goals.

This variability is crucial because it enables effective progression in workouts, facilitating strength building, flexibility improvement, and rehabilitation while also accommodating different body types and movement patterns. The ability to receive support from the springs during certain exercises also enhances stability and control, which are key aspects of effective Pilates practice.
