The most important focus in exercise is the amount of fats that you burn while you are doing that activity. The faster you walk, step or run, for example, the more calories you use per minute. However, high-intensity exercise is difficult to sustain if you are a beginner or you have not exercised for a while, so you may not exercise very long at this level. It is safer, and more practical, to start out at a lower intensity and work your way up gradually.
