What precautions should be taken with pregnant clients in Pilates?

Avoiding supine exercises after the first trimester is crucial for pregnant clients participating in Pilates. During pregnancy, particularly in the later stages, lying flat on the back can compress the vena cava, a major vein that carries blood back to the heart, which can lead to decreased circulation and potential issues for both mother and baby. This makes it essential for instructors to modify exercises and positions, ensuring comfort and safety for the client.

On the other hand, focusing solely on upper body exercises does not address the importance of maintaining overall physical fitness during pregnancy, which includes working on the core and lower body with appropriate modifications. Providing maximum resistance is typically not advisable during pregnancy, as it can put unnecessary stress on the body. Lastly, limiting hydration is contrary to the guidance for pregnant individuals, who need to stay well-hydrated to support their health and that of the developing fetus.
