Rehasul: A New Medical Fitness Facility for Seniors Opens in Sendagi

Introduction

On October 2nd, 2025, Cellsource, a company specializing in regenerative medicine, proudly opened the first branch of its new medical fitness facility, Rehasul, in Sendagi, Tokyo. Unlike traditional gyms, Rehasul collaborates with clinics, employing licensed physiotherapists to assess each member's condition before creating a customized exercise program in coordination with personal trainers.

The Vision Behind Rehasul

Cellsource has established strong networks with orthopedic physicians and has been providing specialized services such as fat-derived stem cell processing and blood product processing to medical institutions. While these services target pain management after onset, Rehasul aims to shift the focus to preventive approaches, particularly for older adults and those with limited mobility due to pain. The goal is to offer a sustainable exercise service informed by medical expertise that can help prevent pain before it arises.

Comprehensive Fitness Approach

Rehasul emphasizes the improvement of four essential physical components: muscle strength, endurance, flexibility, and stability.

- Muscle strength allows easier standing and movement.
- Endurance reduces fatigue.
- Flexibility promotes smooth movement and injury prevention.
- Stability helps to prevent falls, which is a crucial concern for the elderly.

Strengthening all four areas is critical for maintaining a healthy and active daily life, achievable through their unique program, the Balance Method™.
If any of these four components are neglected, the overall function of the body may diminish, making it essential for members to work on all aspects consistently.

Addressing Public Health Concerns

Rehasul is dedicated to addressing the societal issue of the gap between life expectancy and healthy life expectancy. The facility has licensed physiotherapists on-site, offering personal exercise regimens and rehabilitation. From preventive rehabilitation to post-surgical recovery, Rehasul supports the continuation of specialized rehabilitation that typical fitness centers and medical institutions cannot provide uniformly. It represents a new model that combines the strengths of a self-funded rehabilitation facility with those of a fitness center.

Key Features of Rehasul

1. Collaboration with Medical Institutions
The gym works with clinics and hospitals to provide scientifically-based exercise tailored for pain relief and health maintenance.
2. Personalized Program Development
Each member undergoes thorough assessments, including physical function evaluations, functional movement tests, and body composition analysis, to create a bespoke fitness menu.
3. Expert Guidance from Physiotherapists
All training is led by knowledgeable physiotherapists who ensure safe and effective exercise regimens are followed.
4. Beginner-Friendly Training
The programs have been designed to be accessible for beginners, enabling them to improve their physical health at a comfortable pace. With equipment that allows for efficient muscle training, older adults and those undergoing rehabilitation can feel secure engaging in workouts.
