 This is Carlos Castillo. &amp;nbsp;He came in to Skyline with chronic lower back pain that made everyday tasks difficult. &amp;nbsp;He would feel this pain from the moment he woke up to the the time he went to bed. &amp;nbsp;I told him he needed to strengthen his core to help stabilize the the spine and it would stop the pain. &amp;nbsp;Though Carlos was very hesitant when I told him CrossFit would help relieve his chronic back issues, he started up and now over a year and half later Carlos is fitter than ever and pain free!
