Which setting is most commonly used to modify resistance in Pilates exercises?

The setting most commonly used to modify resistance in Pilates exercises is the gear on the reformer. The reformer incorporates a system of springs and pulleys, allowing practitioners to adjust the resistance level based on the gear selected. This flexibility enables a wide range of modifications to accommodate different strength levels, provide support, or add challenge to exercises. Adjusting the gear allows instructors and clients to tailor workouts to individual needs, making it an essential element for achieving specific fitness goals and ensuring safety during practice.

In comparison, while the level of the chair and position of weights can indeed affect resistance, they are not as commonly adjusted as the gear on the reformer for a wide array of exercises. The type of mat does not directly influence resistance but rather the stability and support during mat-based exercises. Thus, the gear on the reformer is the most versatile and frequently utilized method for modifying resistance in Pilates.
