Instead of using a traditional office chair, you can try using an exercise ball for part or all of your working day. Do not use this option if you have a hard time balancing on the ball. Using the exercise ball as your chair can help improve your balance as well as tone your core muscles, just by sitting down at your desk. A fitness ball can assist you with getting in a few squats or ball exercises throughout the day, even if you don't use it as a chair.
You don't have to do the same thing day after day. The benefits of doing this are numerous. If you use the same routine every day, you increase the likelihood that you will become bored with your fitness workout. If your body is acclimated to what you have been doing you may hit a plateau. Keep your routine fresh, and regularly switch things up a little.
Set a schedule for your fitness routine in order to maintain a level of consistency and to reduce the probability of avoiding it. Assign yourself a certain number of days in the week that you must exercise no matter what. When you miss one of your fitness "appointments", be sure to reschedule it. Treat this new appointment just as seriously.
The best way to avoid injury when walking for exercise, is to practice proper form. Pull your shoulders back and keep your spine aligned. Let each elbow drop to a right angle. Ideally the arms should be the direct opposite of your foot. Each stop should start with the heel and then roll forward.
