Yes – when taken in our prenatal classes. Regular mat class is only advised up to 20 weeks because much of the class is performed in a supine position (lying face up) and this can be uncomfortable with the weight of the baby pressing against the diaphragm. Our Prenatal Reformer classes can be modified to allow for a slanted/lifted posture – elevating the head and torso and making Pilates safe throughout pregnancy. Pregnant women produce a hormone called Relaxin that helps the body become looser for childbirth- because of this it is important to limit range of motion some so as not to overstretch muscles. And of course – before beginning Pilates while pregnant it is key to consult your Doctor.
