The GR606 Seated Leg Extension is a commercial selectorized leg training machine. It targets the quadriceps without engaging the lower back, safely and effectively from a comfortable seated position.

Key features include a wide seat, arms that adjust for starting position and leg length, and thick padding. The machine comes with a 220 lb weight stack (upgradeable to 340 lb) with a 1:1 pulley ratio.

Construction: heavy-duty commercial-grade steel tubing frame with black or silver powder-coated finish options, a single pulley with a 1:1 weight ratio, 2000 lb tested nylon-coated high-tensile aircraft cable, fiberglass-strengthened nylon pulleys with sealed ball bearings, and a 220 lb weight stack of precision-milled steel plates (optional upgrade to 340 lb).
