Bulky Lab is an offline private gym located in Motoyoyogicho, Shibuya, Tokyo, Japan. It focuses on “scientific evidence-driven” personal training services. The website highlights that its representative, Akihito Ida, holds a PhD in exercise physiology from the University of Tokyo. Its training philosophy is not about simply pushing clients through extreme high-intensity workouts, but about creating safe, effective, and sustainable training and diet plans based on each person’s physical condition.
Its services mainly include free consultations, one-on-one personal training, diet management, and body-shaping support. On the training side, it emphasizes customization based on the client’s experience, fitness level, and goals, rather than blindly pursuing exhaustion. On the nutrition side, it opposes extreme carbohydrate restriction, fasting, and other methods that are difficult to maintain long term, instead using macronutrient management to balance fat-loss results with enjoyment of food. The site also lists the backgrounds of several trainers, including scientific research experience, physique competition experience, and practical experience progressing from complete beginner to competition placement.
Pricing transparency is fairly good. The enrollment fee is 15,000 yen. The Starter plan without dietary guidance costs 49,800 yen for 1 month with 1 session per week / 4 sessions per month, or 79,800 yen for 2 sessions per week / 8 sessions per month. The Complete plan with dietary guidance costs 260,000 yen for 2 months / 16 sessions, 370,500 yen for 3 months / 24 sessions, and 468,000 yen for 4 months / 32 sessions. There is also a free consultation and a 30-day full refund guarantee, but refunds must be processed in writing at the gym.
The advantages are its professional positioning, emphasis on exercise physiology and sustainable nutrition, making it suitable for people who no longer want to try extreme dieting. Pricing, address, and package information are disclosed relatively comprehensively, and the free consultation also lowers the barrier to making a decision. The drawbacks are that the service is highly dependent on visiting the physical location, making it of limited relevance to users outside Tokyo. The website does not clearly show information such as payment methods or business hours. The packages are not cheap, and the refund process requires an in-person visit, so convenience is average.
It is suitable for people who live or work around Yoyogi-Uehara, Shibuya, or Shinjuku in Tokyo and want to systematically lose fat, build muscle, improve their physique, and are willing to pay for one-on-one guidance. Users in mainland China should generally be able to access the official website directly, but the actual service requires visiting Japan in person, so for remote users in China it is mainly useful as a source of reference information.
