Exercise

At least in mice, exercise is known to increase the number of brain cells1. Exercise not only increases the number of neurons in the brain but also increases their connectivity by increasing cerebral circulation - cerebral circulatory stimulants such as ginkgo, ginseng, and vinpocetine are known to increase the amount of things persons think2.

Exercise is an effective treatment for many patients who do not respond to antidepressant medication3 and, used in the long-term, exercise is a more effective anti-depressant than medication4.

While exercise does spur muscular and cerebral anabolism and optimization, it can cause catabolism if done excessively or without nutritional compensation. Because the increase of serum levels of markers of muscle damage can be mitigated with anti-oxidants5, we can assume this is in part by the generation of metabolic by-products during vigorous activity; but is largely due to the increase in cortisol in response to hypoglycemia6 and the demand to perform an action (such as a rep).

Going into an exercise session, there is a minimum effective dose (in this context not of an ingestible) for the activation of every muscle. It is the minimum dose required to stimulate the maximum anabolism and/or optimization before ones next dose of such exercise. Going above the minimum effective dose will waste nutrients and cause muscle damage.
