Exercise
Exercise is any bodily activity that enhances or maintains physical fitness and overall health and wellness. It is performed for various reasons, including increasing growth and development, preventing aging, strengthening muscles and the cardiovascular system, honing athletic skills, weight loss or maintenance, and also for enjoyment. Many individuals choose to exercise publicly outdoors where they can congregate in groups, socialize, and enhance well-being.
Psychology
Psychology is the science of behavior and mind, including conscious and unconscious phenomena, as well as feeling and thought. It is an academic discipline of immense scope and diverse interests that, when taken together, seek an understanding of the emergent properties of brains, and all the variety of epiphenomena they manifest. As a social science it aims to understand individuals and groups by establishing general principles and researching specific cases.
Sport
Sport (British English) or sports (American English) includes all forms of competitive physical activity or games which, through casual or organised participation, aim to use, maintain or improve physical ability and skills while providing enjoyment to participants, and in some cases, entertainment for spectators. Hundreds of sports exist, from those between single contestants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals. In certain sports such as racing, many contestants may compete, simultaneously or consecutively, with one winner; in others, the contest (a match) is between two sides, each attempting to exceed the other. Some sports allow a tie game; others provide tie-breaking methods to ensure one winner and one loser. A number of contests may be arranged in a tournament producing a champion. Many sports leagues make an annual champion by arranging games in a regular sports season, followed in some cases by playoffs.
Psychology
[Modern psychology] appears as the sickly offspring of average common sense when it is taken as what it professes to be—a science of the inner life. The entire achievements of the so-called science in this respect is outweighed by a single page of Goethe’s or of Jean Paul’s psychology; and it is impossible to evade the bitter truth which Novalis already has summed up, when he says that so-called psychology is one of those idols which have usurped the place in the sanctuary where true images of the gods should stand.
Ludwig Klages, The Science of Character, W. Johnston, trans., p. 16

Exercise and application produce order in our affairs, health of body, cheerfulness of mind, and these make us precious to our friends.

Psychology
Unlike the physicist, the psychologist … investigates processes that belong to the same order — perception, learning, thinking — as those by which he conducts his investigation.
Morris R. Cohen, Reason and Nature (1953), p. 81
