QLI Leg Extension

The QLI Leg Extension (QLE059) is a plate-loaded machine for focused quadriceps training. Its adjustable setup lets each user establish a stable, well-aligned position before loading the movement, and it is built for commercial gyms and advanced strength programs.

The backrest, leg cushion and rotary assembly all adjust with locking pins, so alignment and comfort can be set precisely for each user. A single-leg isolation mechanism lets users train each leg independently for balanced strength development, and the starting position is easy to change. The seat and back cushions are covered in smooth leather that is easy to clean, and the heavy-duty steel frame has an electrostatic paint finish to resist rust.

The QLE059 fits naturally into a lower-body line with a leg curl, leg press and hip machine. Its space-efficient design makes it straightforward to place on a busy floor.
