Engineered for Maximum Shoulder Safety. Built for Everyday Use.
The TB7 was developed by engineers specializing in biomechanics. Unlike narrow bars that compress the shoulder joint, the TB7's 1.6 inch 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 patented center lock system to the NBR foam padding, the TB7 represents a new standard in home fitness equipment.
