Honestly, I didn’t like it, but many persons whom I lived with kept telling me every day how good it was. Since the peer pressure was growing, I decided to go to the gym. It wasn’t until then that I could really understand people when they said exercise really helped a person get organized and keep healthy, physically and mentally. For starters, if you are a lazy person, it is difficult to take the first step. But it is all a matter of committing yourself to something that will provide you with much positive feedback. Once you start exercising and observing positive results, you will actually enjoy it. It takes much effort and a strong will, but it’s worth it. The principal thing to do is to take up a sport you like. If you do, you will start organizing your day in a way that enables you to do whatever you have to, including exercising. You will no longer be a person stressed-out without time to carry on with all your activities. Moreover, exercising is good because it affects you positively in a mental and psychological way. Exercising helps you set specific goals which, along with a strong will, can be achieved. When reaching the goals, you come to know your abilities and your weaknesses, and your self-esteem is enhanced. Any sport relieves stress because it distracts you from thinking about school, work, or your problems, among other things. It helps keep you uplifted and avoid unhealthy habits like indulgence in TV and computer games. Exercising is very important to any person of any age. The positive effects, which I’ve already mentioned, are like a chain. Once you take up a sport that you like, you become better organized. Therefore, you start doing things the right way and enjoy enormous benefits. As a result, you feel good as a healthy human being. You start living your life happily.河南理工大学
