In the past, I have spoken and written quite a bit about stretching. See here, here, here.

Recently, the Journal of Strength and Conditioning Research published some more articles demonstrating yet again that stretching does not help performance and that it actually makes it worse. However, regardless of just how much research is published denouncing stretching, people still do it.

So, the question–again–becomes, why stretch?
