Starting to exercise can be a profound, life-changing experience for a sedentary person. Beginning an exercise routine will change your lifestyle, and it will also have lasting effects on your body. As you begin to exercise, you can expect changes to your heart, fat, muscles, bones and even your brain.
Regular aerobic exercise can make the heart more efficient, reducing your resting heartbeat by five to 25 beats per minute. Regular exercise can also reduce hypertension, commonly known as high blood pressure, reducing your risk of heart disease. While exercise is good for your heart, if you have heart disease, you are at risk of a cardiac event during exercise and should consult a physician before starting a fitness program.
Fat and Muscles
Regular endurance training encourages your body to use its fat stores as a source of energy, meaning that you will lose body fat as you exercise. At the same time, exercise can increase your muscle mass and your muscle mass will -- in turn -- cause you to burn more calories at rest. Overall, exercise -- when coupled with healthy eating habits -- can give you a lower body mass index and a leaner physique.
Weight-bearing exercises such as weightlifting, jogging, dancing and racquet sports can help increase your bone density. As your muscles pull on your bones, the pulling stimulates an increase in bone density. According to the University of Arizona's "Bone Builders" website, "the more bone mass you build before age 25 or 30, the better off you will be during the years of gradual bone loss." Even as you age, weight-bearing exercises can reduce bone loss -- helping to prevent osteoporosis.
According to the "Proceedings of the National Academy of Sciences of the United States of America," the brain's hippocampus shrinks in later adulthood, causing memory problems and posing a risk for dementia. Fortunately, exercise causes the brain to generate new neurons in the hippocampus -- the brain's center of learning and memory. This reverses the shrinking process and can lead to increase spatial memory.
