In the modern office, there are fewer and fewer opportunities for physical exercise, and there is not much time to participate in various fitness classes after work. According to the Los Angeles Times, health experts from the United States provide you with six kinds of exercise opportunities, which you can seize while working in the office. 1. When working at the desk, we spend most of our time sitting in chairs, so it is very important to keep the correct sitting posture. Choose a chair with a backrest and armrests. When working, be sure to keep your forearms parallel and your knees at 90 degrees to your feet. In addition, you can put a cushion on the lower part of your back. 2. When copying documents, you can relax your neck and shoulder muscles, turn your head rhythmically, and stretch your limbs while waiting. All these exercises can help you relieve the stress brought to your body when you are working at your desk. 3. Doing moderate-intensity physical exercise in the elevator as little as possible can help people strengthen their heart function. So, take the elevator as little as possible and take the stairs instead. If your office is on the fifth floor, walking upstairs to and from work every day is the best exercise. Don't rush back to work in the office after lunch break. Walking after a meal can not only help digestion, but also help you relax all parts of your body and your mood. 5. Do a squat with your feet apart, the distance is equal to the width of your shoulders, then slowly squat with your hands on the chair and get up and stand. Do this repeatedly 10 times, and continue to do it after a short rest 10 times. This exercise can help you strengthen your thigh and back muscles. 6. After drinking tea or coffee and working for a while, stand up and make yourself a cup of tea or coffee. When making tea or coffee, you can stand on one leg in turn and raise one leg to the maximum; Or stand with your legs together and bend down to let your palms touch the ground.
