Background
Physical activity is associated with a lower incidence of common mental health disorder, but less is known about the impact of cardiorespiratory fitness (CRF).

Long story made short – get off your arse its good for you…..
Poor CRF is shown to be correlated with reduced mental health quality over time. I agree Chris, what is not shown is the magnitude and quality of benefit from degrees of CRF above some perceived baseline. I have been gobsmacked by the research over time (admittedly some quite small studies) that demonstrate benefit from astonishly small amounts of exercise. I recall one study that demonstrated some sort of benefit from vigorous exercise for one minute every hour during the working day. And I truly believe, from my own eperience, that there is major benefit from slightly longer periods of vigorous exercise (say 30 minutes a day) in association with quite modest amounts of general strength training (we’re talking some work here).
Good one.
