While there has been public debate about whether running is good for your health for a long time, experts agree that running has more benefits than the costs. Some people are concerned that the pressure on your knees and ankles can be detrimental . While this can be true, there are many things that you can do to reduce your risk of injury. You should always go to a doctor for advice before you begin any type of exercise program. Then, a good pair of running shoes can be helpful as your feet hit the ground. They will help protect your ankles by providing stability to your feet. So it is good idea to visit a specialty(专业) running shoe store. The staff there can suggest shoes which are ideal for your running style. In order to learn the proper form, you may get some advice from a friend who has been running for some time, or even join a running club. They can provide good tips as well as some support and encouragement for you. Lastly, it is important to start out slowly. When it comes to getting in shape and losing weight , short bursts of speed followed by periods of slower movement would be proper. Aim for around 30 minutes of exercise a few days a week. As you get better, you can increase your speed. Always allow your body to rest in between heavy exercise as your muscles need time to bring energy back.
