You need back flexibility for many exercises. Examples are the Bench Press & the Pendlay Row which involve arching of the back. Lack of back flexibility will make it difficult to use a correct technique. Back Extension-Flexions are an easy way to improve your back flexibility. Here’s how to perform them.


Back Extension-Flexion Setup

  • Get on all fours
  • Arms straight, elbows locked
  • Hands & knees shoulder-width apart
  • Hands directly under the shoulders
  • Knees directly under the hips
  • Feet relaxed
