Have you ever looked at a runner as she stretches out after a run and wondering if maybe that could be you someday? If you can walk, you can run. For motivation, check out these reasons to slip on your running shoes and hit the pavement. Running works your cardio-vascular system. If you’re new to running, you’ll want to work your way into it, walking for a minute, then running for a minute, on and off as you make your way to running without breaks. Every time you run, you'll notice your heart rate races to a fat burning or cardio exercise range, which strengthens your heart and lungs. Running is great defense against osteoporosis. Bone density is increased with weight bearing exercise, so running increases bone density in a way biking or swimming could not. Running is a surefire way to burn excess calories. If you weigh 150 pounds and run for thirty minutes at a ten-minute-mile pace, you’ll burn 330 calories. Compare that to the 150 calories you’d burn walking at a fifteen-minute-mile pace. Running will destress you. While running, you'll feel like an invincible machine; after running, you'll feel relaxed and rejuvenated. A good run increases your body’s production of endorphins, which make you feel like everything is going to be all right. Not to mention how amazing that post-run shower will feel; it's like no other shower. Running can be done just about anywhere and costs very little. Just buy some tailored running shoes (go to a running store and get fitted for best results) and find yourself a track, trail, or street. It's best to run on soft surfaces (treadmill, dirt path, or track) for about fifty percent of the time, saving your joints from the harder pounding on the pavement or cement sidewalks.
