I would encourage members to receive an evaluate and possibly consider a well rounded fitness program including nutrition, flexibility and strengthening. Ergonomics is great to reduce stressors on the human frame; however, nutrition and fitness is key because a decondition body will affect the human frame negatively no matter how much ergonomics. Flexibility enhances circulation as well as release tightness prone muscles (outer bigger muscles) that cause deeper protective muscle (postural muscles - core/shoulder blade stabilizers) to shutdown, which affects human frame alignment, breathing (postural muscles aid in breathing), etc. One needs to treat to whole body not just parts (example: lower body restriction [foot] can eventually affect the upper body [neck, arms, etc.]). There is a condition called thoracic outlet syndrome, which affects the nerves or arteries/veins down the arms causing circulation, fatigue, weakness, etc. This condition can chronically cause inflammation, CTS, tennis elbow and/or golf elbow. Overall, there are other factors involved too including autoimmune disease, arthritis to name a few, but as males most of us do not see a doctor for annual physicals (me too but have an apt this month)! I've worked with a professional football team, pharmaceuticals and been trained/educated by osteopaths and fully understand that one needs to look at the whole body not just parts of the body for a healthy body! I better stop before I bore the members/team too much!! Just my 2-cents!
