The fixator muscle for back extension is primarily the transversus abdominis. This muscle stabilizes the pelvis and lumbar spine during movements, allowing the extensor muscles of the back, such as the erector spinae, to effectively extend the vertebral column. Additionally, the multifidus also plays a role in stabilizing the spine during back extension.

The iliopsoas muscle is stretched during hip extension. This muscle group is made up of the psoas major, psoas minor, and iliacus muscles. Stretching the iliopsoas can help improve hip flexibility and relieve hip tightness or discomfort.
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 fixator of a muscle stabilizes the muscle at the point of origin.

The fixator is one of many muscles used during situps. The fixator muscle stabilizes one part of your body when you move another part.
i think is the deltoid muscle but I'm not sure tbh
Back extension primarily works the muscles in the lower back, specifically the erector spinae muscles.
The functions of a fixator muscle is the stabalizing of the orgin of the prime mover so that the prime mover can act more efficiently. Fixators steady the proximal end of a limb while movements occurs at the distal end. EX: The scapula is a freely movable bone that serves as the orgin for several muscles that move the arm. When the arm contracts the scapula must be held steady.
