Coretrim Station Collaborates with Yokohama City's "Women's Health Promotion Support Program" to Offer "Low Back Pain Prevention Exercises" for Elementary and Junior High School PTA Groups at Desired Schools

Coretrim Station, a specialized back conditioning studio operated by Coretrim Co., Ltd. (Representative Director: Tomoaki Nishina), an affiliate of Nihon Sigmax Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; Representative Director and President: Yosuke Suzuki), is pleased to announce that it has registered a 'Low Back Pain Prevention Exercise' course for 'Hama-Yell,' a program supporting women's health that will be launched by Yokohama City in April 2026. 'Hama-Yell' is a health promotion support project for women of child-rearing age, promoted by Yokohama City. Each registered course will be introduced by Yokohama City to approximately 500 elementary and junior high schools in the city, and courses will be held according to the wishes of each school as part of PTA group activities. ■ Background: Women's low back pain is an often-overlooked health issue; supporting the health of busy child-rearing generation women Women of child-rearing age are busy daily with childcare, housework, and work, making it difficult to secure time to learn about their own health. Regarding chronic low back pain, it is not uncommon for symptoms to appear after pregnancy and childbirth, but women often prioritize others, neglecting their own care and living without sufficient treatment. It is also not uncommon for women to suddenly experience severe pain, such as a slipped disc, which interferes with childcare, housework, and work. Such low back pain in women is one of the health issues often overlooked by both those around them and the women themselves. Coretrim Station provides conditioning aimed at the fastest possible improvement of low back pain by teaching body mechanics that reduce strain on the back, based on medical evidence. We believe that this course can contribute to the health promotion of busy child-rearing generation women through 'Hama-Yell,' Yokohama City's new initiative, which led to the registration of this course. ■ What is the 'Low Back Pain Prevention Exercise' offered by Coretrim Station? ・Easy-to-understand explanation of the causes of recurring pain, categorized by low back pain type ・Introduction of postures and movements that tend to strain the back ・Guidance on low back pain prevention exercises that can be done at home ・Lectures on daily life tips to lighten the burden on the back ・Target: Parents of children attending approximately 500 elementary and junior high schools in Yokohama City ・Number of participants: Up to about 50 people ・Duration: 45 minutes ・Format: On-site event ・Required venue equipment: Space to arrange a chair and a yoga mat for each person. ・Fee: Free ・Application deadline: One month before the desired event date ■ Comment from the person in charge Long-term back pain can often be significantly improved by simply changing how one uses their body.
