Quad Isolation.
Engineered for elite gyms, athletic facilities and commercial fitness centers. Built with heavy-duty steel, smooth biomechanics and uncompromising durability.

Selectorized leg extension with cam-shaped resistance and adjustable back / thigh pads.
The GROWL Leg Extension drives a smooth cam-shaped resistance curve that matches quad strength — full contraction through the entire range on a commercial stack.
Every GROWL machine is built on 11-gauge structural steel with laser-cut components, sealed precision bearings and a tactical powder-coat finish. Commercial-grade upholstery, smooth cable and cam paths, and clean modern styling that holds up in high-traffic facilities for years.
Whether you're outfitting a private gym, athletic facility or commercial fitness center, our team can help design the perfect equipment package.
