While exploring the corners inspired by @VernonGriffith4 I found myself in a fly at the end of the extension of this core exercise. This is a learning process to bring the form into full control but the experiment worked. My clients have enjoyed using the initial extension exercise in their program. Keep learning! Keep creating! Get in motion and make it a beautiful day!
