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.

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.
The vastus medialis is involved in leg extensions.
Well on my 94 Topaz I used a spark plug socket with a built in swivel and a extension with 15 degree angle cut into it. The extension came as a set 3 sizes all with 15 degree angles cut into them. I bought them change plugs on a 80' Buick Skylark V6. Good Luck!
