Downward-Facing Dog Pose (Adho Mukha Svanasana)

This posture is great for building resistance in the abdominal muscles, along with strengthening the spine.
a. Step One
Rest your body on all fours, with your hands underneath your shoulders and knees aligned under the hips.
b. Step Two

Keep your hands and feet on the ground and push your hips outward, keeping your feet straight.
c. Step Three
Balance your weight on the forearms and fingers and keep your head hung low.
d. Step Four
Balance your weight in such a way that the bulk is removed from the arms, thereby reducing muscular strain.
e. Step Five
Keep your legs as straight as possible and your heels flat on the floor.
f. Step Six
Exhale as you relax your posture and gradually sink to your starting position. Rest for 5 counts and repeat.
