The BUILT Strength Infinite Series Back Extension is a commercial-grade selectorized machine built to load the posterior chain directly and repeatedly, spinal erectors, glutes, and hamstrings working through a controlled extension arc with smooth, consistent resistance from a 200 lb weight stack. Pin-select adjustments keep load changes fast between sets, supporting everything from warm-up volume to heavy working sets.
