PT: Cressey/Robertson - ROM?

I posted this in EC’s PT thread from last week, so sorry for the repetition.

I’ve had a lot of success with your postural articles and they’ve carried over to the rest of my gym work. I work in an office, and probably will for the forseeable future, which means 9 hours a day sitting on my ass. Obivously, this affects a lot of things, specifically posterior chain and hip flexors.

So I recently had the revelation that I need to compensate for this 9 hours of postural “training” by fixing the other side of the chain. I do this by stretching the hip flexors, and focusing most workouts on the posterior chain. Two questions:

  1. How do I tell I’ve gotten everything back to “normal”? Since I’ve worked in offices for 12 years now, normal to me is the way I am. How do I tell I’ve reached the point that ROM/strength is about right, versus I’m doing too much to compensate?

  2. Any other suggestions in/out of the gym for addressing this situation?
