The BUILT Strength Throwback Series Hack Squat runs on a fully enclosed linear bearing system — the enclosure keeps the carriage tracking on a precise, frictionless path while protecting the bearings from dust, chalk, and the wear that accumulates in high-traffic commercial environments. The result is smooth, quiet movement that stays consistent session after session, even under the heaviest lower-body loading.

Hip-height plate loading puts the horns at the most ergonomic position for fast, safe plate changes — no crouching to floor-level, no overhead reaching. Dual-height start positions accommodate athletes of different sizes for safe entry and exit, and a large non-skid footplate supports narrow, wide, and staggered stances for targeted quad, glute, and calf emphasis. Six integrated storage positions keep the floor clear and plates within reach throughout the session.
