    This intro series to muscle movement vs muscle stability can help us determine what’s needed to build the exercise. Also, that reminder that we build (not change) the exercise is important. Thanks!

    I am so grateful to both: Lady Simona, and Dr. Muscolino for their invaluable, in-depth and simply practical tuition; there’s never enough anatomical knowledge that a Pilates Teacher should possess, not so much to be proud of it, but to understand how the human body works. I humbly ask for more:)
