> The evidence for exercise as a treatment for depression is weak at best.

That's what the link you give says...

> You should probably not recommend exercise as a treatment for depression.

But it doesn't say that.

It does say "When compared to psychological or pharmacological therapies, exercise appears to be no more effective, though this conclusion is based on a few small trials.", in which case, can anything be recommended?

The NHS still recommends exercise for treating depression, at least in some cases: http://www.nhs.uk/conditions/stress-anxiety-depression/pages... & http://www.nhs.uk/Conditions/Depression/Pages/Treatment.aspx
