The training movement performed in the LTL is a lateral, or side bending, flexion movement. The hip lock system helps to encourage a specific lateral bending exercise resulting in a transverse mobilization and joint movement in the lumbar-thoracic spine. The activation of this movement requires the activation and support from the body’s core muscles to ensure a controlled and well coordinated movement. The goal of this lateral flexion movement is to strengthen the primary muscles for this movement pattern providing both support and increased movement to the lumbar and thoracic spine.
