Choosing the Right Exercise
Other activities
New forms of exercise, especially exercise classes, are always being developed. Some become widely popular and others are less popular but no less effective. Some people are more motivated to exercise when they vary their routine, and newer popular workouts can improve motivation. However, more familiar forms of exercise and even some activities that are not traditionally described as exercise (such as ballroom and other forms of dancing) can be equally effective. Interactive video games that encourage physical activity (sometimes called exergames) may provide some benefit, but they are not a substitute for a regular exercise program.
