Leg Extension Machine MF-LE100
The MF-LE100 Leg Extension Machine isolates the quadriceps with a biomechanically correct cam design that matches the quadriceps strength curve. Variable resistance through the range of motion — heavier where you’re strongest, lighter at the stretch position. 250 lb selectorized stack with 5 lb incremental add-on. Adjustable back pad (5 positions) and tibia pad (3 positions) for customized fit. Range-of-motion limiter for knee rehabilitation protocols. Contoured seat with side bolsters for hip stability.
