Lie on your stomach with your legs straight behind you. Place your palms on the ground by your armpits, elbows bent behind you.
Push through your hands to slowly lift your head and shoulders off the ground, arching your back while keeping your hips and thighs on the ground. Arch back as far as is comfortable, keeping your elbows slightly bent to lessen the stretch and straightening them to intensify it.
Actively roll your shoulders back and down away from your ears, elongating your neck. Keep looking in front of you, or if you want more of a chest stretch, drop your head back between your shoulder blades. Stay here for a few breaths.
Slowly lift your hips and shift your butt back until it rests on your heels, bowing your back and coming into Child's Pose. Your arms should be straight out in front of you, palms pressing into the ground. Stay here for a few breaths.
Lift your hips again and shift forward to return to Cobra Pose.
