If you consider how often we sit (ahem, slouch), it's not a huge surprise that many of us suffer from minor upper back pain. I mean, we probably spend the majority of our day seated whether we're driving, at our desks, eating or watching tv. No bueno, my friends, because I'm willing to bet that many of us are hunched over. This puts a lot of strain on the upper back, shoulders and neck, and weakens the chest over time. To counter that, I've put together 5 yoga poses to alleviate minor back pain.
