There is no one theory or hypothesis that has been universally accepted to explain the link between exercise and mental health. Instead, several different hypotheses have been proposed. These can be split into two categories: (1) physical or bio-physical and (2) psychological or psychosocial.

It has been shown that exercise has a positive effect on mental health, but in practice it can be difficult to pinpoint the exact reasons why. This may be because a combination of factors is leading to improvements in mental health, rather than one factor alone. Also, because people differ greatly, explanations for improvements to mental health may vary according to the person concerned.
