In addition to preparing for delivery, what else do Kegel exercises support?

Kegel exercises primarily aim to strengthen the pelvic floor muscles, which play a crucial role in supporting the bladder, urethra, and other pelvic organs. By engaging in Kegel exercises, individuals can improve the strength and endurance of these muscles, which helps maintain bladder control and can prevent or alleviate issues such as urinary incontinence.

While strengthening lower back muscles, improving circulation to limbs, and alleviating morning sickness are important aspects of overall health during pregnancy, they are not the primary focus or benefit of Kegel exercises. Thus, the emphasis on pelvic floor support highlights the specific benefits Kegel exercises provide in relation to bladder and urethra health, making this option the most accurate in the context of the question.
