Six asanas that will boost your fat-burning ability and improve your healthAs we age and our lifestyles catch up with us (read increased hours sit-ting on the desk and staring at the computer, eating fast food mindlessly and ODing on caffeine to keep the eyes open) the first thing to crash is our metabolism — the process through which the body breaks down food into nutrients and decides what to keep and what not to. A slow me-tabolism (aka hypothyroidism) means that the body stores more fat and absorbs less nutrients. Not just does this leave you on the wrong side of the weighing scale, but also in danger of suffering from high cholesterol, high blood sugar and high blood pressure and poor blood circulation. Try yoga which will not only get you in great shape but also boost your overall health (a slow metabolism is linked to poor immune system).Yoga asanas focus on different areas in the body, helping you target the systems that are holding your metabolism back. Here are six asanas that will do just that for you:Garudasana Stand with knees slightly bent. Now lift your right leg and cross it over your left thigh, and hook your foot behind your left calf. Now, sink your hips down as you would if you were sitting on a chair. Cross your arms at your elbows and wrists in front of your chest. Hold for 45 seconds and return to start position and then switch sides. In addition to building strong, lean leg muscles, this pose energises the entire body and helps with digestion.Matsyasana Lie on your back. Place your palms under your buttocks. Raise your el-bows and lean on them by pressing them into the floor. Lift your chest up toward the ceiling so your back is arched. Bring your elbows towards each other and drop your head back towards the floor. This pose stretch-es the front of the neck and calms the body.
