What FIST does

FIST X (피스트엑스) is a Seoul-based boutique fitness operator that runs small-group "Body Shape Training" classes combining CrossFit, barbell, weight, and functional movements across two physical clubs in Seoul — Seoul National University Station (서울대입구) and Guro Digital Complex (구로디지털단지). Founded in 2021 by Lee Chang-yeop (Dan), a former competitive CrossFit athlete and coach, the company serves adults in South Korea seeking combined fat loss and muscle gain through a single membership. Each session runs FAT BURN (cardio-leaning fat loss) and VOLUME (anaerobic muscle gain) simultaneously, letting members pick their focus per class; sessions also include InBody body composition analysis and personalized diet guidance.

The company's signature technical layer is its AI Weight Recommendation System, which it describes as the world's first AI-driven loader for the four major barbell exercises (shoulder press, bench press, squat, deadlift). The system logs each member's daily weights and recommends an optimal load for the next session based on individual performance history, with the broader curriculum drawing from 1,900 curated barbell, weight, and functional movements. The business model is recurring subscription memberships priced privately (not publicly disclosed), with customer acquisition driven primarily by word-of-mouth and member testimonials; a 100% refund guarantee applies to members who attend 3+ times weekly and see no body composition change within 4 months. The company is privately held, incorporated as 주식회사 팀피에이치세븐 (Team P H Seven Co., Ltd.), and operates entirely through its two physical locations with no app or digital distribution channel.
