First-of-Its-Kind Low Oxygen Training Experience by Hyroxi Champion, Wataru Nakamura
On August 29, 2026, the flagship HYROX training center, "High Altitude", celebrated its grand opening in Shimokitazawa, Tokyo. The event featured a special experience with Japanese representative Wataru Nakamura, highlighting the effectiveness of low oxygen training for HYROX competitors. Conducted in an ultra-modern facility designed to simulate high-altitude conditions, this innovative training method is drawing considerable attention among fitness enthusiasts.
Participants were overwhelmingly satisfied with the event, with 100% rating their experience as satisfactory or better. A significant percentage expressed interest in further training or joining the program, indicating a promising trend in the growing popularity of HYROX in Japan.
HYROX is a fitness race comprising an 8 km course that alternates 1 km of running with various workouts. The race involves eight distinct challenges: SkiErg, Sled Push, Sled Pull, Burpee Broad Jumps, Rowing, Farmers Carry, Sandbag Lunges, and Wall Balls. It is designed for all skill levels, offering various participation formats such as Individual, Doubles, and Relay. With upcoming competitions in Osaka and Makuhari in January and August 2026, respectively, the race is rapidly garnering attention from both runners and strength trainers in Japan.
With over 60% of the competition composed of running and ergometer workouts, maintaining aerobic capacity is crucial to preventing fatigue towards the latter stages of the race. VO2max, lactate threshold, and recovery capabilities are essential metrics that significantly influence performance. Training in a low oxygen environment—equivalent to 2,500 meters above sea level—provides effective cardiovascular stimulation with less physical strain compared to training at sea level. This makes it an attractive training method for endurance sports like marathons while also enhancing performance in HYROX.
During the experience day, participants engaged in a talk session on the benefits of low oxygen training and a practical HYROX workout in a simulated low oxygen environment. Participants ranged in age from their 20s to 40s, with the majority expressing high satisfaction with direct guidance from Nakamura and the unique training setting.
Among the feedback, comments included the intensity of the low oxygen workout and how it effectively challenges cardio capacity. Participants noted varying experiences from the exhilarating difficulty of the exercises to discovering a new training modality.
The studio is the only facility capable of accommodating all eight HYROX events within a low oxygen environment, designed to directly impact cardiovascular fitness. The facility adjusts oxygen levels while maintaining regular air pressure, thus minimizing the risk of altitude sickness, allowing participants to benefit from high-altitude training without experiencing adverse effects.
The Shimokitazawa studio offers various programs tailored to different skill levels and training goals, including introductory courses for beginners and advanced training sessions for experienced participants.
A strategic relationship with Jousai University’s track team enhances program quality, focusing on developing explosive strength and recovery capabilities necessary for competitive success.
To foster the burgeoning interest in HYROX, the High Altitude Shimokitazawa Studio is committed to offering specialized low oxygen training programs that cater to a broad audience. By providing a welcoming environment and expert guidance, the studio aims to elevate the standard of fitness training in Japan.
The introduction of this innovative training method, once reserved for elite athletes, promises to transform fitness practices for everyday individuals.
