Another tremendous yoga posture, this one is great for reducing belly fat too. Lie flat on your back on your yoga mat. Bend the knees and keep the feet a little apart from each other. Keep your feet and palms flat on the ground. Now lift your hips and torso up towards the ceiling. Maintain the position for a few seconds. Gently lower the body back to the ground. Repeat. Regular practice of some or all of the above positions s bound to flex our abs muscles and burn the extra flab around the belly.
