SFE Selectorized Seated Leg Extension & Leg Curl Machine with 250 lb Weight Stack

SFE Selectorized Seated Leg Extension & Leg Curl Machine with 250 lb Weight Stack

Train both the quadriceps and hamstrings from a single compact strength station with the SFE Selectorized Seated Leg Extension & Leg Curl Machine. This commercial-grade dual-function machine combines two essential lower-body isolation exercises with extensive adjustability and a 250 lb selectorized weight stack with a 1:1 pulley ratio.

Designed to accommodate a wide range of users, the machine features an adjustable back pad, extended seat pad, multiple movement-arm positions, an adjustable leg roller, and an eight-position thigh pad. The extensive adjustment range allows users to customize positioning and range of motion for both leg extensions and seated leg curls.

The back pad moves forward and backward and has been tested with users ranging from approximately 4'10" to 6'10". Additional back pad stops and the extended seat provide greater positioning flexibility for taller athletes and users with longer legs.

Laser-engraved numbering on key adjustment points makes preferred settings easy to identify and repeat between workouts. Textured rubber handles provide additional stability during demanding sets, while supportive padding helps maintain a comfortable training position.

Despite its extensive functionality and substantial 403.45 lb net weight, the machine maintains a relatively compact footprint, making it suitable for commercial gyms, personal training studios, athletic facilities, and serious home gyms.
