"Stretch Hearts" has a shape similar to the shoulder blades and pelvis, which are the core of the body. The calculated unevenness stimulates various parts of the body. It fits regardless of body shape, so it can be used by many people, and can relieve muscle fatigue and increase flexibility. "Stiffness in the muscles around the shoulder blades can also be a cause of stiff shoulders. The muscles of the shoulders are connected to the shoulder blades, so it is important to loosen them together with the shoulders. Use Stretch Hearts for easy stretching! Loosen and detach the muscles around the shoulder blades." This is Mr. Hosaka's opinion. "Stiffness in the muscles around the pelvis can also be a cause of muscle fatigue. The inability to bend forward is often due to the piriformis muscle, located below the dimple on the buttocks, becoming stiff. If you loosen it, it will quickly become soft." This is Mr. Hosaka's opinion. It has been stored at home almost unused after purchase, so I believe the condition is good. Please understand that there are some minor scuffs. If you have any questions, please ask before purchasing.
