Learning to breathe properly (at the age of 67!) not only helps to reduce any tension I may be feeling but has also made me more aware of both my muscle action and spinal movement. Likewise, discovery of my “core” and the way it affects not only my stomach but also my sides, back and hips, has also been positive and has encouraged me not to hunch my shoulders but to keep an upright posture not only during exercises but in everyday movement.
