Relieve Heartburn with the Belly Vacuum
As your baby grows and puts more pressure on your tummy, your diaphragm may get weaker and start letting more acid from the stomach sneak up into the esophagus. This exercise keeps the barrier between your diaphragm and esophagus strong.
Stand with good posture, inhale through your nose and bring arms overhead, clasping hands with palms facing up (A). Exhale through your nose, then contract your abs to spread ribs apart without inhaling, feeling an internal stretch in back and core (B). Hold for 3 to 10 seconds and repeat 10 times.
