Camel will open up your back and chest even further while clearing out your passageways. If you can't reach the heels of your feet or it's too intense, then place your hands on your lower back, fingers pointing down, and bend back until you feel the stretch. If not completed properly, this pose can be very strenuous on your back, so don't overexert yourself.
What to Do: Check out the step-by-step intro to Camel Pose. Hold the pose for five breaths, come up slowly, and then rest in Child's Pose.
