- a practice could be also a rehearsal or a review such as practicing a session in preparation for a public performance . Here the action is devoid of any regularity ,just a one time review , while the word "exercise" can't be used in such an occasion. - "practice" is a process of repetitive actions leading to learning or evolving physically or spiritually ( practicing a religion) ,the meaning is associated with the aim of the repetitive actions. Whereas the meaning of "exercise" is more associated with the function and the momentary performance of the action.

Hello Abdullah, Exericse: Involves using one's mental or physical powers in doing something, performing a function or exerting an influence. You can exercise in the gym (physical act) or exercise power or authority in a working place for example. The physical exercise is marked by regularity ,continuity (usually part of a time schedule), but it is not necessarily habitual. Whereas "exercise " in the sense of using one's power, authority or control etc ... in doing something is in a form of a habit and attitude not necessarily within the bounds of any time limitations. The difference between "to exercise" and "to practice" activities is as follows: - "to exercise" concentrates on the physicality and functionality of the actions. To exercise in the gym is for example to perform the movements or use the equipments etc... ,while "to practice" something involves other aspects that are not necessarily physical in their nature. You practice learning English,which is more of a mental effort. Practicing a game or yoga could involve both mental and physical efforts. - "to exercise" is regular but not necessarily habitual . When you exercise you do sort of a regular training. "to practice" on the other hand is more habitual as part of one's life style ,even if it doesn't hold necessarily a regular schedule . It involves repetition and systematic training ( not necessarily regular though) to learn something.
