Second trimester pregnancy exercise
As your belly gets bigger, your pregnancy exercise routine will start to change. Back pain might start to be more common as your lower spine curves, and swimming is one of the most effective ways to find relief. It’ll also improve circulation and boost muscle tone—a big plus, since heavy weight lifting is no longer a good idea. If you feel comfortable doing so, it’s also safe to jog and bicycle, but skip any exercises that have you laying flat on your back, since it can restrict bloodflow to the baby.
