The Importance of Weight Loss and Exercise
Carrying around too much weight feels uncomfortable, and it can also damage your health. According the Centers of Disease Control and Prevention (CDC), obesity rates have skyrocketed in the United States in recent years. As of 2010, more than one-third of American adults have obesity, defined as having a body mass index (BMI) of 30 or higher. Body mass is derived by dividing weight in pounds by height in inches squared, and then multiplying the result by 703 (weight (lb) / [height (in)] 2 x 703). You can calculate your body mass by following these three steps:
1.Multiply your weight in pounds by 703.
2.Calculate your height in inches squared.
3.Divide the resulting number from step 1 by the resulting number in step 3.
Obesity can lead to a number of serious health problems, including heart disease, diabetes, stroke, and some types of cancer.
Combining exercise with a healthy diet is a more effective way to lose weight than depending on calorie restriction alone. Exercise can prevent or even reverse the effects of certain diseases. Exercise lowers blood pressure and cholesterol, which may prevent a heart attack.
In addition, if you exercise, you lower your risk of developing certain types of cancers such as colon and breast cancer. Exercise is also known to help contribute to a sense of confidence and well-being, thus possibly lowering rates of anxiety and depression.

To receive all of the health benefits of exercise, you’ll need to mix in some higher intensity exercises. To get an idea of how hard you are working, you can check your heart rate. The basic formula for determining your target heart rate is to subtract your age from 220 and then calculate 60 to 80 percent of that number.
Talk to a trainer or your healthcare team to help you determine your best intensity for each workout. Those with special health concerns such as an injury, diabetes, or a heart condition should consult a physician before beginning any fitness program.
Aerobic
No matter what exercise program you implement, it should include some form of aerobic or cardiovascular exercise. Aerobic exercises get your heart rate up and your blood pumping. Aerobic exercises may include walking, jogging, cycling, swimming, and dancing. You can also work out on a fitness machine such as a treadmill, elliptical, or stair stepper.
Weight Training
A big advantage of working out with weights is that, in addition to shedding fat, you’ll build muscle. Muscle, in turn, burns calories. Talk about a healthy feedback loop! Experts recommend working all the major muscle groups three times per week. This includes: •abs •back •biceps •calves •chest •forearms •hamstrings •quads •shoulders •traps •triceps
Yoga
Yoga is not as intense as other types of exercise, but it can help you lose weight in other ways, according to a recent study by researchers at the Fred Hutchinson Cancer Research Center. The study found that people who practice yoga are more mindful about what they eat and, therefore, less likely to have obesity.

Healthy lifestyle habits to consider include:
•walking or riding your bike to work or while running errands
•taking the stairs instead of the elevator
