What is the best way to use this applicator for muscle tension after sitting at a desk all day?

For post-desk tension, the large 260×590 mm format is well-suited to cover broad areas. Focus on your upper back and shoulders: lie on your back with the mat positioned vertically so it supports your spine from mid-back to the base of your neck. You can gently roll your shoulders or do small, slow arm circles to help the spikes make contact with different muscles. For lower back stiffness, place the mat horizontally under your lower back while lying down, with your knees bent and feet flat on the floor. You can also sit on the edge of a chair and place the mat behind you, leaning back against it to target specific spots. The principle is to let the many pressure points encourage microcirculation and provide a strong sensory signal that can shift your body's attention away from stiffness. A session of 10-20 minutes can fit well into an evening wind-down routine.
