The rectus femoris becomes active in a leg extension because one of the actions of the rectus femoris is hip extension, as well as knee extension. The rectus femoris crosses both the hip and knee on the anterior side of the body. When the leg is extended it is one of the primary movers, whether it be straight leg extension, in which case it is the rectus femoris, illium and psoas muscles. In knee extension the rectus femoris works in conjunction with the other 3 quadriceps. However, in the case of a seated leg extension the rectus femois is less active, due to it already being shortened for the hip extension.
Leg extension exercises focus on quadriceps.

I like to do hamstring curls to work the lower part of my hamstrings which dead lifts don't really touch. But my gym is gay and only has those seated hamstring curl machines where you actually SIT on your hamstrings, the most stupid thing i have ever seen, yes sit on the muscle you are trying to work. Anyway I can do improvised curls on the leg extension machine, if I face the seat.

A fixator for a leg extension exercise is a piece of equipment that helps stabilize and secure the leg during the movement, typically found in a leg extension machine. It is designed to isolate the quadriceps muscles by restricting movement in the hip and knee joints, allowing for more targeted muscle engagement and better form. Fixators can help enhance the effectiveness and safety of leg extension exercises by providing proper support for the legs.
