Many of my clients come to me without awareness of the order and names of Pilates exercises. These exercises were designed to flow into each other and balance muscles groups. For example, targeting arms, and then legs, spinal extensions and flexion of the spine. When you do an disorganized work-out than the underutilized muscles may not be targeted. This does not mean you rigidly stick to the order, but clients should know and understand the value in order to become more self-sufficient in their workouts.
