Core Diet is a brand under Medsapiens Co., Ltd., a brand leading healthy lifestyles and culture, making efforts to create health, happiness and beauty. The Deep Roller is a product developed for effective care of body postures and health by stimulating the inner muscles that affect the stability and posture of the spine through excises using the foam roller, which is based on the principle of effective manual therapy, joint isolated movement technique (JIMT). The design allows the joints of the spine (cervical spine, thoracic spine, ribs, lumbar spine, sacrum, iliac bone) to return to its normal position with acupressure exercises using own weight. The right posture of the spine can be maintained without burdening the body, based on clinical knowledge of a professional spine therapist.
