Hi, my name is Wilson Foo, the author of 31 Simple Stretches You Can Do At Your Desk. First of all, I’d like to congratulate you for obtaining this book. You now have before you an incredible resource to improve your work day and your physical health - 1 stretch for every day of every month. Now, you may be wondering to yourself, how can a few simple stretches make a great impact to your workday? Let me share with you how it has improved mine.Have you ever felt extremely tired while working at your desk? I certainly have. Before I started writing this book, I was a litigation lawyer. This job sometimes entailed long hours and a great deal of stress.The common perception of litigation lawyers is that we spend most of the day on our feet arguing in court. While that is partially true and oral arguments in courtrooms are indeed an integral part of the work, much of the time was actually spent at my desk, staring at the computer, poring through reams of documents and drafting written work.Sitting at the same position for a long time can leave us feeling extremely weary. Staring at a screen all day long also tends to strain the neck and back. Not having to move around means that our legs also don’t get much chance to stretch and we start to feel restless all the time.Even at home, I worked on some other projects of my own as well. I am also an app developer and have published some desktop, web and Android apps online. Spending long hours at the desk coding on the weekends made it even worse as I did not get a break from my sedentary lifestyle.I felt that I needed to contribute to the world by helping others in the same situation. Everybody who works, whether at home, or in an office, can benefit from stretching once in a while. This tends to relax our muscles and gives us better productivity. After a good stretch, your work may still be the same and perhaps nothing has changed - but everything has changed, because you feel more alert and able to tackle the challenges ahead.After stretching, I feel rejuvenated and refreshed, at least for the moment. As there are 31 stretches, you can do each stretch for every day in the month - or you can do one a day. The key is to do whatever suits you the most.May you ever be happy and relaxed as you stretch those muscles!
