Prenatal yoga is a great way to help you slow down and control your stress, while strengthening and lengthening your body to maintain a healthy body for pregnancy and preparing it for birth. Yoga helps to keep the chest open, improve breathing, relax the shoulders and increase leg circulation, which may be reduced by additional weight. Remember to check with your doctor. Use yoga at your own intensity and level of difficulty, to feel better and calmer.
Keep your feet at least hip-width apart in all standing and seated postures.
No twisting (if any keep them open twists and incredibly light on your upper chest)
It is best to avoid inverting in your first trimester.
Use only gently backbends during third trimester to protect your abdominis.
