Turning the knees out with the legs bent puts the hip flexors at a disadvantage while placing a rolled up towel under the lumbar curve allows for a contraction of middle rectus against a load by providing a fulcrum for full range trunk flexion.

Koch, Blom, and Jacob advanced this understanding in developing the "abmat".
