The BodyKore GR606 Seated Leg Extension is a commercial selectorized machine that isolates the quadriceps from a supported, seated position. By locking the hips and lower back into a wide, padded seat, it concentrates the work on the quads without loading the spine, making it a safe, effective way to build knee-extension strength and shape the front of the thigh. It is at home in clubs, rehab and training studios, and premium home gyms, serving both beginners and advanced lifters who want clean lower-body isolation.

A 220 lb selectorized weight stack of precision-milled steel plates drives the resistance, adjusted in seconds with a single pin so sessions stay uninterrupted. A 1:1 pulley ratio delivers a direct, honest load through the full leg-extension arc with the smooth, quiet feel of genuine commercial equipment. When a facility needs more capacity, the stack upgrades to 340 lb, giving stronger athletes meaningful room to keep progressing on the same machine without any frame change.

The GR606 is built on a rolled steel oval-tubing frame finished in a durable black or silver powder coat, engineered for years of heavy, repeated use. Adjustable arms set the starting position and accommodate different leg lengths so the rotation aligns with the knee, while the wide seat and thick padding add comfort and stability through each rep. These adjustments keep the movement biomechanically sound and the quadriceps fully engaged from start to lockout.

With a footprint of 69 in. by 49 in. and a height of 65 in., the GR606 weighs 544 lb and stays firmly planted through heavy extensions without anchoring. BodyKore backs the frame with a lifetime warranty plus multi-year coverage on stacks, pulleys, and bearings, making it a durable commercial investment. First Place Fitness Equipment stocks it across our Florida showrooms in Jacksonville, Orlando, Tampa, Sarasota, and Miami.
