What is the purpose of the "shoulder blocks" on the Reformer?

The shoulder blocks on the Reformer serve the primary function of providing stability and preventing the shoulders from slipping during exercises. This stability is crucial, as it allows practitioners to maintain proper alignment and control, enhancing the effectiveness of their workout. By anchoring the shoulders, the blocks help ensure that participants can focus on executing movements without the distraction of maintaining balance, which can lead to injury or improper technique.

In contrast, while the shoulder blocks might influence how some exercises are executed, they are not primarily intended for intensifying shoulder muscle workouts, facilitating pulling and pushing exercises, or cushioning the neck. Instead, their design emphasizes support and stabilization to create a safe and effective Pilates experience.
