Planks; you either love them or hate them! They are AMAZING at strengthening your core, which in turn, builds back strength to reduce lower back pain, improve balance, and perfect posture. A low plank (or elbow plank) helps strengthen your core by giving those abdominal muscles, more of a challenge since you aren't activating your shoulder & arm muscles to help hold yourself up as much as if you were performing a traditional high plank.
