YOGA FOR BACK PAIN

1)  Bhujang asana

This asana is also known as cobra asana as the posture resembles that of an alarmed cobra. You need to lie prostrate on the ground and inhale. Raise your torso to the maximum possible level with the help of your hands. Inhale while you are raising your body and hold your body and your breath in this position and maintain this position as long as possible.
Get back into the normal position and exhale.

2) Naukasana:

The naukasana pose comes from the words "nauka," which means boat, and "asana," which refers to the relaxed position you take to do the yoga move. When you do a naukasana, your body form resembles a boat. Hence, the naukasana pose is often referred to as the boat pose. A naukasana can be done on your stomach, which is the more common form, but a version can also be done while you lie on your back. Both forms of the naukasana may improve your physical and mental health.

STEPS:

To do a naukasana pose on your stomach, lie flat on the floor with your hands resting along your sides and your head turned to one direction. Raise your head, keeping your chin on the floor, and slowly bring your arms above your head. Raise your upper and lower body at the same time so you are resting on your abdomen. Hold the pose for three to five breaths, then slowly lower yourself back to the starting position. To do a naukasana on your back, lie flat on the floor with your legs extended in front of you and your palms resting on the floor alongside your thighs. Slowly raise your head off the floor and your feet up toward the ceiling. Hold the pose for several breaths, then lower yourself back to the starting position.
