The most powerful on-going effects on your upright posture come from tightness somewhere in your Anterior Chain (these myofascial tissues include Quadriceps, TFL – Tensor Fascia Lata – and your anterior Adductors, to Abdominals and Psoas, right through to your Pec area.)
CRITICAL RECOMMENDATION for Passive Stretching:
RELAX deeply into the area you are stretching; or you will never achieve new flexibility, and you may even injure yourself. Subconsciously not letting go of muscle tension as you stretch is a common and critical error to avoid.
The most common example of this error is when people stretch their calves on the edge of a set of stairs – subconsciously pushing their forefoot into the step as they lower the heel for a stretch. NOT good.
But it also really applies to the stretches you are doing today for Quadriceps, Hip Flexors, and Abdominal areas!
