3. Go for a walk
A good old trick is just walking. It is easy to start and you can go for a walk anywhere and at any moment. Pay attention to your body – it’s supposed to be relaxed and pain-free. Start with short distances taking no longer than 15-20 minutes. Later you can increase the distance, but it will depend on your state and condition. The longest you are advised to spend walking would be an hour per day – the time that is needed to stay fit.
