Yes. B-MONSTER is a dark boxing fitness program using punching bags and mitts — it is not a sparring gym. No boxing experience is needed; staff explain basic punching combinations at your first session. It is designed for people who want a high-intensity, full-sweat workout.
B-MONSTER's studio combines music, lighting, and visual effects for an immersive atmosphere. You train to DJ music in a darkened room. The dim lighting removes self-consciousness — beginners can focus on movement without feeling watched. Your eyes adjust before the class starts.
B-MONSTER offers unlimited monthly plans and drop-in options. Monthly unlimited membership typically runs ¥10,000–¥15,000 depending on the studio and plan. First-trial pricing is often discounted (around ¥500–¥1,000), letting you experience the class before committing to membership.
