: Essential for absorbing impacts from throws and falls. Performers practice both front and back bridges to build up the trapezius and sternocleidomastoid muscles.
In 2015, Yuna set her sights on the Self-Transcendence 3100 Mile Run, widely considered the most grueling ultrarunning event on the planet. This 3100-mile journey, which takes runners through the streets of New York City, would test her physical and mental limits like never before. Coach Takahashi and Yuna meticulously prepared for the challenge, developing a bespoke training plan that would ensure her optimal performance.
The choice of Yuna Mitake as the star of JBD-297 is particularly potent given her real-life background. Her experience as an MMA instructor and her muscular, toned physique create a powerful juxtaposition. She is not a passive or fragile figure, but a strong, athletic woman willingly undergoing a form of "training" that is the thematic opposite of her real-world discipline. This contrast is likely a significant part of the film's appeal. The "Extreme Training" title is thus a deliberate play on words, taking the concept of physical discipline and applying it to a completely different, more extreme, context.
While most lifters focus on progressive overload (adding weight), Mitake focuses on volume overload. Her baseline workout includes 1,000 bodyweight squats, 1,000 push-ups (in variations: diamond, wide, archer), and 1,000 sit-ups. She does not stop for water. She does not pause for breath.
