Latest Mobility Training Gym "4D Performance Lab" and Japanese Jiu-Jitsu Gi Brand "Posture_Method,Dimensions_" Launch Collaboration Apparel

4D-Stretch Inc.'s training gym "4D Performance Lab" announces an apparel collaboration with Japanese jiu-jitsu gi brand "Posture_Method,Dimensions_ (P.M.D_)". The first collection in this collaboration features a total of 4 items, based on the concept of "mobility" and "range of motion" advocated by 4D Performance Lab. The lineup allows for smooth enjoyment from gym workouts to daily life and relaxation.

The collaboration theme is "Change your actions, change your future."

If your daily actions change, your body will change. If your body changes, your future will change.

This collection combines the philosophy of 4D Performance Lab with the craftsmanship of Posture_Method,Dimensions_ as Japanese-made activewear, offering both functionality and lifestyle appeal.

"Dimensions"__Shared Thoughts and Background of Both Brands

This collaboration was realized through a connection with Mr. Masaki Takeura, director of Posture_Method,Dimensions_.

As Posture_Method,Dimensions_ learned about the philosophy and activities of 4D Performance Lab, they found common ground in the idea of unlocking the body's potential and the concept of connecting daily life with performance, which led to the start of this collaboration.

Mobility training, as proposed by 4D Performance Lab, is not just about strengthening muscles or stretching, but about training the body to move more naturally, flexibly, and efficiently.

Meanwhile, Posture_Method,Dimensions_ develops wear that connects body movement with daily life, rooted in martial arts culture.

This collection expresses the shared philosophy of "body movement," "posture," and "daily performance" in the form of apparel.

"From Gym Workouts to Daily Life"

We pursued not only ease of movement during training but also a comfortable feel and stylishness that uplifts the wearer in daily life. The design balances style and relaxation, making it enjoyable for both work and leisure.

The cotton t-shirt creates a relaxed and luxurious feel with its oversized silhouette.

The dry t-shirt uses fabric with antibacterial and odor-resistant processing, supporting comfortable gym workouts. It is also recommended for daily use in hot weather or outdoor activities.

Furthermore, we aimed to incorporate positional graphics to enhance awareness during gym training through body movement, gaze, and visual effects.

Comment from Daiki Torii, Representative of 4D Performance Lab

At 4D Performance Lab, we aim to unlock the body's potential through mobility training called "4D Stretch."

In this collaboration with Posture_Method,Dimensions_, we have expressed our core concepts of "mobility" and "range of motion" in apparel that can be felt not only during training but also in daily life.

As the message "Change your actions, change your future." suggests, small changes in daily actions transform the body and change the future.

We would be delighted if this collection serves as a catalyst for positive changes in your body and actions, not only during gym training but also in your daily life.

Comment from Kojiro Kondo, Director of Posture_Method,Dimensions_

Upon hearing about the philosophy and activities of 4D Performance Lab, I felt many commonalities with Posture_Method,Dimensions_ and strongly desired to collaborate.

In this collection, we aimed for wear that expands the range of motion, from gym workouts to daily life.

We prioritized a comfortable feel and stylishness that uplifts the wearer in daily life, as well as a balance that can be enjoyed both on and off duty.

For the cotton t-shirt, we focused on a relaxed and luxurious feel through an oversized fit.

For the dry t-shirt, we designed it to support comfortable gym workouts with fabric treated for antibacterial and odor resistance.

We also aimed to incorporate positional graphics that enhance awareness during gym training through body movement, gaze, and visual effects.

We hope this collection can be enjoyed naturally, both in the gym and in daily life.
