The first stretch is called the pelvic tilt. You will roll back onto your back with your knees bent. You want to imagine pushing your belly button into the ground, or push your back flat onto the ground like you are squishing something. You can put your hand under the curve of your back, and try to push your back into your hand. Make sure you are breathing and not holding your breath while doing these exercises. Next you will do a bridge. Push your bottom up off the ground, but try to do this slowly, and do one segment of your back at a time curling upward. Then slowly go down the same way, one segment at a time.
