How many springs should be used for the single thigh stretch?

For the single thigh stretch on the reformer, using two springs is generally the recommended approach. This choice provides the right balance of resistance to effectively engage the core and mobilize the legs during the exercise. The added spring tension helps in stabilizing the pelvis while allowing for effective leg movement. This allows the practitioner to maintain control and proper alignment throughout the movement.

When using one spring, the resistance might be insufficient for many individuals to feel adequate engagement, making the exercise less effective. Conversely, utilizing too many springs can create excessive resistance, potentially compromising form and making it difficult to perform the movement accurately and safely. Hence, two springs is typically the optimal choice for ensuring an effective workout for the single thigh stretch.
