Breathe in to fill your lower lungs. Your belly will push your left hand up as you do this. Your right hand won't move.
Then breathe out. Your left hand will fall as your belly falls. Do these steps 8 to 10 times.
Next, breathe in as you did before, but don't stop after your left hand pushes up. Continue to breathe in. You will feel your upper chest expand and push your right hand up. Your left hand will fall a little as your belly falls.
Breathe out slowly through your mouth. As you breathe out, feel the tension leaving your body. Both your hands will fall. Do this exercise for 3 to 5 minutes.
