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

Nihon Sigmax Co., Ltd. (Head office: Shinjuku-ku, Tokyo; Representative Director and President: Yosuke Suzuki)'s affiliate, Coreslim Co., Ltd. (Representative Director: Norichika Nishina), which operates the specialized lower back conditioning studio "Coreslim Station," announces the registration of its "Back Pain Prevention Exercise" program with "Hama-eru," a women's health promotion support program launched by Yokohama City in April 2026.

"Hama-eru" is a health promotion support project for mothers promoted by Yokohama City. Each registered program will be introduced by Yokohama City to approximately 500 elementary and junior high schools in the city, and programs will be held at schools requesting them as part of PTA group activities.

Background: Women's back pain, an often overlooked health issue; supporting the health of busy mothers

Women in the child-rearing generation are busy daily with childcare, housework, and work, making it difficult to secure time to learn about their own health. Regarding chronic back pain, many cases show symptoms appearing after pregnancy and childbirth, but women put their own needs aside and spend time without sufficient care.

It is not uncommon for women to suddenly experience severe pain like a slipped disc, which interferes with childcare, housework, and work. Such back pain in women is one of the health issues often overlooked by both those around them and themselves.

Coreslim Station provides conditioning aimed at the fastest possible relief from back pain by teaching body usage that does not strain the back, based on medical evidence. We believe that this program, through Yokohama City's new initiative "Hama-eru," can contribute to the health promotion of busy mothers, leading to the registration of this program.
