“Training adduction and abduction exercises for the hip compound is integral for healthy flexion of the hip, and can even contribute to healthy lower back, knee, and neck movement,” says Neiman.
Circumduction is a combination of flexion, extension, adduction and abduction. Circumduction can be best performed at ball and socket joints, such as the hip and shoulder , but may also be performed by other parts of the body such as fingers, hands, feet, and head. [ 24 ]

A duction is an eye movement involving only one eye. [1] There are generally six possible movements depending upon the eye's axis of rotation: Abduction refers to the outward movement of an eye. Adduction refers to the inward movement of an eye; Supraduction / sursumduction / elevation; Infraduction / deorsumduction / depression; Incycloduction ...
Since only a small part of the eye called the fovea provides sharp vision, the eye must move to follow a target. Eye movements must be precise and fast. This is seen in scenarios like reading, where the reader must shift gaze constantly. Although under voluntary control, most eye movement is accomplished without conscious effort.
This "Figure Eight" exercise works the muscles differently by moving the head and keeping the eyes in place. Stare at a fixed object straight ahead. Close one eye.
The face pull is a weight training exercise that primarily targets the musculature of the upper back and shoulders, namely the posterior deltoids, trapezius, rhomboids, Latissimus dorsi as well as the biceps. [1] The face pull is considered an important exercise for shoulder health and stability. [2]
In fact, each of the six extraocular muscles exerts rotational forces in all three planes (elevation-depression, adduction-abduction, intorsion-extorsion) to varying degrees, depending on which way the eye is looking. The relative forces change every time the eyeball moves – every time the direction of the gaze changes.
