Understanding Spring Tension

The type of spring that is used on Pilates equipment is called a “tension/extension spring”. When this type of spring is stretched from its resting position, it exerts an opposing force proportional to its change in length. In other words, the more you stretch a spring, the more opposing force it provides.

“In Pilates, sometimes less springs will translate to more load on the muscles and vice versa. For example, when doing the Side Split on the Reformer, one light spring means to a lot of load on the hip adductors (assuming the exercise is executed with the utmost precision and quality). If extra load is added, not only will the load on the hip adductors decrease, at some point, more work will transfer to the hip abductors.” Rael Isacowitz

In addition, unlike traditional weight training, some exercises can actually be made more challenging by decreasing the spring tension on the Reformer, rather than continually increasing it.” Sarah Baker
