When is the last time you stopped and thought about the merits of flexibility training? When life gets busy there is always something that needs to be tossed to the sidelines so you can focus on what is important.

We get it and we’ve been there. Burning calories trumps rolling out your shoulders. But despite your best efforts to make the most of your workout, you could actually be doing more harm than good if you skip the stretch.
