Because of the focus on core strength and lack of stress to the body, Pilates is a perfect choice of exercise both during and post-pregnancy.  Keeping the abdominal, back, and pelvic floor muscles strong during pregnancy can lead to a more comfortable delivery and make the postnatal body recover more efficiently.  Because Pilates is highly adaptable, your Pilates session will be modified based on your trimester.  Post-delivery, your core will slowly re-awaken and again your workouts will be modified to better support your needs and goals.
