The fascia in our body is created by how we move. It is aligned in a transverse plane from the lat to midback, to opposite hip. By performing planks, bridges, and crawling before performing dynamic movements in our warm-up we resync the firing sequence of the muscles to fire the way they should. If you are sitting in a chair all day this is especially important. When you reset the core the body recognizes that is has stability and then mobility in the extremities opens up. A practical application would be to perform side planks, front planks, glute bridges, and crawling before loading a movement pattern. Planks are a great option before squats as front planks improve external rotation of the hips, while side planks improve hip internal rotation. Give it a try on your next warm-up and see how you feel.
