Engineered for Maximum Shoulder Safety. Built for Everyday Use.
The TB7 was developed in Seoul by engineers specializing in biomechanics. Unlike narrow bars that compress the shoulder joint, the TB7's 40mm grip distributes load evenly, supporting safer overhead motion. The wide stance reduces internal rotation stress, improving muscle recruitment in the lats, delts, and upper back.
Every design decision prioritizes long-term joint health and sustainable training. From the precision-engineered friction-grip system to the medical-grade foam padding, the TB7 represents a new standard in home fitness equipment.
