Aerobic exercise is the type that moves large muscle groups and causes you to breathe more deeply and your heart to work harder to pump blood. It's also called cardiovascular exercise. It improves the health of your heart and lungs.
Examples include walking, jogging, running, aerobic dance, bicycling, rowing, swimming and cross-country skiing.
The term weight-bearing is used to describe exercises that work against the force of gravity. Weight-bearing exercise is important for building strong bones. Having strong bones helps prevent osteoporosis and bone fractures later in life.
Examples of weight-bearing exercises include walking, jogging, hiking, climbing stairs, dancing and weight training.
Weight training, or strength training, builds strength and muscles. Calisthenics like push-ups are weight-training exercises too. Lifting weights is a weight-training exercise. If you have high blood pressure or other health problems, talk to your family doctor before beginning weight training.
The best exercise is the one that you will do. Walking is considered one of the best choices because it's easy, safe and cheap. Brisk walking can burn as many calories as running, but is less likely than running or jogging to cause injuries. And it doesn't require any training or special equipment, except for good shoes.
Walking is an aerobic and weight-bearing exercise, so it is good for your heart and helps prevent osteoporosis.
