Poor digestion may result in food allergies, especially as you get older, says, Pennsylvania. To improve digestion, we suggest trying an exercise called Agni Sara, or strengthening the fire.

Here are instructions for performing the exercise: Stand with your feet about three feet apart, toes pointed slightly outward. Bend your knees slightly and place your right hand on your right thigh and your left hand on your left thigh. Your fingers should be pointing inward, toward the opposite leg. Bend your neck so that you’re looking down at your stomach. Breathe out completely. Then suck in and lift your abdomen without taking a breath. Now pump your stomach muscles, pushing your abdomen in and out without breathing. Pump this way 10 to 15 times, then relax, stand up straight and breathe. Repeat the exercise three times per day.
