Whether you have attended a few barre or Pilates fitness classes or have yet to try them, you have probably heard of "the tuck." Different classes and instructors call it different things, including "dropping your tailbone," "pelvic tilt," "tuck your pelvis under," and "heavy tailbone." These all mean the same thing and, when done right, it has great benefits for your strength and your posture.
