Publisher: Magazine House Release Date: February 6, 2025 Magazine Format: A-size Keywords: Tarzan February 27, 2025 issue, Tarzan, Tarzan Publisher: Magazine House *The regular edition of Tarzan No. 896 and the special edition of Tarzan No. 896 have the same content, with only the cover differing. A dramatic transformation of life: A major study on "miracle muscles"! The iliopsoas muscle, the only muscle connecting the upper and lower body, is now a hot topic. It's an inner muscle that's attracting attention from professionals such as trainers and physical therapists. One trainer checks this muscle first when caring for athletes' bodies, and one instructor warns that people whose iliopsoas muscles aren't functioning properly are experiencing many problems. It's related to performance, of course, but for Japanese people who sit too much, the shortening and hardening of this iliopsoas muscle leads to fatigue, poor posture, disruption of the autonomic nervous system, and accelerated aging... it's truly the root of a vicious cycle in the body. It's a crucial muscle for the body, yet its general recognition is still surprisingly low. Therefore, Tarzan will provide an easy-to-understand explanation of its function, along with a check of your own iliopsoas muscle's stiffness and weakness, an introduction to everyday bad habits, and a feature that approaches exercises to stand, loosen → relax, condition, and train. The centerfold feature is "Adult Running School" using the iliopsoas muscle. We've asked medalist Dai Tamesue to teach us the tips for running fast. Also, the second feature focuses on the "buttocks training" that's also attracting attention. We've been taught home glute training by Tomo Okabe, a charismatic trainer for beautiful buttocks. This is a book that focuses on the muscles you should be paying attention to now, the "iliopsoas muscle" and the "gluteal muscles." The gravure feature showcases the best body of Yoshinori Masakado of Aぇ! group, who debuted last year, after two months of rigorous training, so be sure to check it out.
