Which of the following exercises is BEST suited for a client in the second trimester of pregnancy?

The seated double leg pumps on the Wunda Chair is an appropriate exercise for a client in the second trimester of pregnancy due to its stable seated position and focus on controlled movement. This exercise promotes pelvic stability and engages the core without putting undue pressure on the abdomen. It allows the client to maintain a good posture while avoiding excessive strain on the lower back.

During the second trimester, many women experience changes in their body and increasing fatigue. Therefore, exercises that are not only supportive and stable but also allow for safe modifications are ideal. Additionally, seated exercises can accommodate the growing belly and are generally more comfortable for pregnant clients during this stage.

In contrast, other options like the short spine massage on the Reformer may involve movements that are less engaging in terms of stability and could be challenging to perform correctly with a larger abdomen. The swan on the trapeze table involves lying on the stomach, which becomes uncomfortable and may not be advisable during pregnancy. Standing side splits on the Reformer requires balance and stability while standing, which can be particularly challenging and riskier for pregnant clients as their center of gravity shifts. Thus, the seated double leg pumps best meets the safety and comfort needs for clients in this stage of pregnancy.
