Kettlebells and Back Pain

There is a great article in the New York Times that describes an 8 week study done by researchers in Denmark.  They took two groups of middle aged pharmaceutical workers, mostly women, and told one group to exercise however they liked.  The second group worked out 20 minutes, 3 times a day with kettlebells.  The kettlebell group reported less back, shoulder and neck pain.  Of course!  Check it out!
