Commercial selectorized leg extension and prone leg curl combo with adjustable ergonomics — built for COMMERCIAL GYMS
The BodyKore Isolation GR643 Leg Extension / Prone Leg Curl is a dual-function lower body machine engineered to strengthen both the quadriceps and hamstrings in one efficient station. Designed for commercial facilities, it allows seamless transition between seated leg extensions and lying prone leg curls.
With a 220 lb selectorized weight stack (upgradeable to 340 lbs) and a smooth adjustment system, users can quickly switch exercises and resistance between sets. The back pad adjusts into a lying position while the seat tilts upward for comfort, ensuring proper alignment and effective muscle activation.
Rated over 1000 lbs and built for durability, the GR643 is a versatile, space-saving essential for serious leg training.
