Isolation Exercise

Isolation Exercise: An exercise that isolates, or attempts to isolate, one muscle or muscle group and involves the action of only one joint. Typical examples are biceps curls, triceps curls, leg extensions, leg curls, and shoulder raises. It is impossible for one muscle to work in total isolation. For instance, even during the biceps curl the scapula must be stabilized and the the shoulder joint fixed, which requires the work of other "fixator" muscles. However, an isolation refers to one joint undergoing active movement in one direction, as opposed to a compound (multi-joint) exercise, which involves the coordinated movement of several joints.
