@drmondragonofficial: Amazing back crunches! Deep and hollow. Overhead presses compress the thoracic outlet. Any movement with the arms above 90 degrees is going to compress it. The body is able to handle this movement perfectly only if there is NO impingement anywhere! The biomechanics of the human arms in motion lends itself however to the impingement of this area leading to symptoms of weakness, numbness, tingling, aching, etc. in the upper extremities and localized regional pain. Working with a chiropractor can help you understand and locate potential problem areas to not only improve your performance, but lead to a more pain-free lifestyle. #chiropractor #asmr #relax
