Muscle Blueprints Launches ‘THE CORE’: Visualize Muscle Activity for 40x Effectiveness in Just 10-Minute Workouts
Muscle Blueprints, Inc., headquartered in Shibuya, Tokyo, and led by Representative Ryuta Kinugasa, has officially launched “THE CORE,” an online personal training service. This program utilizes the company’s self-developed wearable electromyography (EMG) sensor, “KinnikuPhone,” to visualize muscle activity in real-time during training sessions. Launched in January 2026, THE CORE is designed to maximize the time performance of busy executives by eliminating reliance on subjective “feelings” and instead employing scientific evidence and sensing technology.
To commemorate the launch, a special campaign offers the first 10 registrants a 40% discount on the monthly fee for the initial three months.

Background: Why Rely on “Feelings” for Physical Training When Business is KPI-Driven?
For executives, time is a crucial asset. However, many who visit gyms for health maintenance often find the return on investment (ROI) extremely low, citing wasted travel time and unclear effectiveness. Ryuta Kinugasa, CEO of Muscle Blueprints and a researcher from UCSD (University of California San Diego) and RIKEN, discovered through his research that there is approximately a 40-fold difference in muscle activity between self-training and training with real-time feedback on muscle activity. THE CORE was developed to eliminate the uncertainty of “feelings” and “spirit” by leveraging cutting-edge technology to provide the most direct and effective solutions for executive body optimization.
Three Technical Distinctions of the New Service, “THE CORE”
1. Biofeedback with the Proprietary Device “KinnikuPhone”
Members wear the dedicated “KinnikuPhone” device to measure muscle electrical signals (EMG) during training. The smartphone application provides real-time feedback on muscle contraction as waveforms and sounds. This eliminates subjective errors of “feeling it work” and visualizes subtle muscle reactions in millisecond increments, which even professional trainers cannot discern with the naked eye.
2. Exceptional Time Performance: 10 Minutes, Twice a Week
Based on data, coaching focuses precisely on the forms that generate the highest muscle activity, eliminating the need for lengthy sessions. Each session lasts only 10 minutes. Even with remote guidance via platforms like Zoom, objective coaching based on numerical data achieves an exercise intensity comparable to 60-minute gym sessions. This transforms brief spare moments into highly efficient health investments.
3. Scientific Evidence-Based Analysis Reports
The acquired waveform data is analyzed and recorded by the app, accumulating as a valuable asset. Feedback is provided based on logical numerical values, indicating how much output has increased since the previous session and how much the target values have been exceeded. This program is ideal for executives who wish to manage their physical development as they would manage business PDCA cycles.

Comment from Representative Director Ryuta Kinugasa
Ryuta Kinugasa stated, “The evolution of technology is rewriting the common sense of body building. The era of sacrificing health with the excuse of ‘being busy’ is over. In just 10 minutes, your body can change scientifically. I am confident that this sensor technology, the culmination of my research life, will extend the healthy lifespan of Japan’s leaders and contribute to maximizing their performance.”
