The BUILT Strength Infinite Series Linear Hack Squat is built around a high-performance linear bearing system that eliminates friction across the entire movement — the carriage glides without drag or deviation from the first inch of descent to lockout, letting athletes drive maximum force into the platform without fighting the machine. Two racking positions and adjustable range-of-motion stops give every user precise control over start height and squat depth, from full depth reps to explosive partials.

An extra-large non-slip foot platform supports narrow, wide, staggered, and calf-focused stance variations — opening the full range of quad, glute, and calf emphasis options from a single machine. Starting resistance of 125 lb per arm and a max capacity of 8 × 45 lb plates per arm delivers a loading range serious enough for the strongest athletes in any commercial or performance training facility.
