What is the purpose of the D parts of the session format in Pilates?

The purpose of the D parts of the session format in Pilates is to focus on endings. This component serves to wrap up the session efficiently, allowing for a smooth transition as participants conclude their practice. It emphasizes the importance of proper closure, ensuring that students can reflect on their experiences during the session, reinforce what they've learned, and integrate the benefits of the exercises into their bodies. This aspect of the session is crucial for promoting awareness, relaxation, and a sense of completion.

The other choices do address important elements of a Pilates session, but they do not specifically capture the intent of the D parts. Introducing new exercises typically occurs earlier in the session rather than at the end, while feedback is generally exchanged throughout the class rather than reserved for the end. Assessing progress is also an ongoing process and not limited to the conclusion of a session. Thus, the focus on endings is the key role of the D parts in the session format.
