Gupta, I totally disagree with your statement concerning posture and FMS being only for athletes wanting to excel.
Too many of the issues, low back pain, knee pain, chronic shoulder issues, etc, etc, are the result of poor posture. Many of the problems I see are due, to a large extent, to a lack of body awareness…. the people aren't even aware that they have a poor postural habit or that such habits can cause problems. A good postural evaluation can not only make them aware of these bad habits but can be used to plan a corrective exercise program.
As for the FMS, the more I read about this, the more I believe the fitness work I do with the general populace and the weekend warriors is all wrong…. basically I'm trying to do what Gray Cook warns against… trying to put fitness on top of a poor or dysfunctional stability base. These "hidden" asymeteries and movement dsyfunctions cannot not only lead to injuries in elite athletes but to many that are participating fitness programs. As a strength & conditioning specialist and yoga instructor I'd go so far as to say anyone that is beginning a resistance program or yoga class should go through the FMS. In fact, 4 of the trainers at the fitness center where I work part time are going to an FMS worshop to get trained in the FMS. The plan is that our fitness center will make the FMS part of the initial evaluation for all new members.
