We are rarely still. We are constantly bombarded with stimuli and many of us believe we must always be doing something, we do not allow ourselves moments of stillness or the opportunity to just be. Then we move and are shocked when we find one shoulder is more flexible or one leg is stronger or something is just so much harder on one side than it is on the other. We live asymmetrical lives, but are surprised to find that reflected in our bodies.
One of the many reasons I love Pilates is that it forces me to accept my imbalances and allows me the opportunity to find the stillness in the center of all the movement.
