Wide-range stretching for hard-to-reach back areas! Suffering from shoulder and lower back pain? Many people experience this, especially after long periods of smartphone use or desk work...
In such cases, [back stretching] is crucial!
The back has large muscles connected to the shoulders and lower back, and they are used in various daily movements. Poor posture, like hunching, can put even more strain on these muscles, leading to shoulder and lower back pain...
Therefore, it's important to loosen the entire back over a wide area through stretching, not just the areas where you feel pain!
Introducing the Core Stretch Band! The band vibrates at super high speeds, and by applying it to your back and moving your body, you can achieve wide-area back stretching that is difficult to do on your own.
Developed under the supervision of the leading stretch specialty store [Dr.Stretch], incorporating their methods. The feeling of relief after stretching is truly amazing!
