Running is an efficient calorie-burner. In a study, it is reported that people who underwent a planned exercise burned 2,800 calories a week and dropped 30 pounds. On average, a 150-pound individual burns 100 calories per mile, and if a runner is committed to running five miles per day, he can lose more or less 500 calories daily, and 2,500 after five workouts a week. Therefore, it is wise to ask your doctor if your body is up for the challenge. Your physician will consider your age, weight, fitness level, and special conditions (breathing or heart problems) to derive a sound decision. Having accurate information on your body will also help you in choosing a running program. Heart rate monitor. This is important to people who like to keep track of their heart performance and improvements in the pulse. With a chest strap and wrist unit, heart rate monitor displays information on the heart rate and calories burned.

Humbly start at low-levels. You may run or walk shorter distances when beginning the running program. You may also opt to run at least once a week initially.

Pain is most pronounced when running downhill or on cambered surfaces, when knees are stretched, and even when simply walking upstairs and downstairs. At the onset of pain, running must be immediately stopped. Intake of non-steroidal anti-inflammatory drugs (NSAID), cold therapy, and massage can reduce the pain. In time, the body becomes more efficient in processing the limited air. Runners who swim often have excellent breathing efficiency. Breathing rhythms Sometimes, in long races (or even those short races) a runner may lose focus and is thrown out of his breathing rhythm. It could be caused by the simple forgetting to concentrate on the breathing or its pattern.
