[A Posture Supporter with Heart, the Ultimate Product!!] The posture supporter was born to protect the spinal health of modern people. According to survey data, it has been found that over 23% of adults aged 18 and over spend more than 5 hours a day engrossed in computers and smartphones. This lifestyle leads to a lack of exercise and muscle weakness in modern people, increasing the risk of slouching. If this situation continues, the body's posture and basic metabolism will also worsen, and confidence and health tend to be lost. The company has taken this problem seriously, and after over a year of research and effort, also under the supervision of a posture guidance expert, this slouch correction belt was born! This posture support belt has a simple yet lightweight design and provides the strongest support for the back. It corrects slouching "without strain," "without pain," and "unconsciously," guiding you to the most beautiful posture! is the origin of the design, which is filled with sincere thoughts for posture health! [The Secret of Maximum Correction Power, You Can't Go Back to Slouching!!] Some posture supporters have a structure with only a belt that lacks support, or are supported by plastic bones that are easily broken, and there is a problem that they do not have an actual corrective effect. To address this series of issues, we specially invited Mr. Hiroki Shimazaki, a Japanese physical therapist, as an advisor, and relying on the structure of human engineering, we carefully developed a "metal bone" version back muscle supporter. When you wear it, you will immediately feel a comfortable sensation as if your back is being pulled! And, it provides stable support even when worn for a long time, unconsciously maintaining your posture at all times, and it will not easily collapse. This is the "core secret" of the posture belt's excellent corrective power!
