Force USA G-Series Accessories for Leg Extension and Curl

Complete your leg workout on the G-Series: The official accessories for leg extension and leg curl allow for isolated quadriceps and hamstring training right on your Force USA All-In-One Trainer. An add-on that turns a multi-purpose machine into a full-fledged leg trainer.

Why Isolated Leg Training Is Essential

Squats and leg presses provide a comprehensive workout for the legs—but they alone are not enough for balanced leg development. Leg extensions and leg curls isolate the quadriceps and hamstrings separately—which is important for symmetry, injury prevention, and sport-specific training in running, jumping, and strength sports.

This accessory is designed for Force USA's G-Series All-In-One Trainers. It integrates into the machine's existing structure, eliminating the need for expensive standalone leg extension and curl machines.
