9. Fish Pose
This and the next pose are restorative poses meant to help calm the mind and lower your heart rate after your yoga session. In this first reclining pose, arching your back allows the abdomen to open up, which helps the next pose rid the body of impurities, says Lewis. Depending on your level of flexibility, you can do this pose with your legs straight in front of you or with your knees bent and feet flat on the floor.
