What is the benefit of the "Knee Stretch" exercise on the Reformer?

The "Knee Stretch" exercise on the Reformer is particularly effective for strengthening the quadriceps while also engaging the core. During this exercise, participants typically start in a kneeling position, using the strength of their legs to push against the resistance of the reformer. This action targets the quadriceps, which are essential for knee stability and movement. Additionally, the exercise requires the practitioner to maintain a strong core to support the spine and ensure proper alignment throughout the movement. Engaging the core not only enhances stability but also facilitates proper posture during the exercise, leading to a more effective and safer workout. Overall, this combination of lower body strength and core engagement is a key benefit of the Knee Stretch exercise.
