Cycling is another type of aerobic exercise with wide appeal and value. You can use a stationary or regular bike. Cycling may be ideal for individuals who, due to arthritic or other orthopedic problems, are unable to walk for an extended period of time without pain or difficulty. A program that combines walking and cycling may provide cardiovascular benefits without inducing the limiting pain as quickly. Cycling is also a good choice for people who are greater than 50 pounds overweight. It helps the heart without the mechanical stress on the back, hips, knees and ankles that walking can cause. One drawback – if you cycle outdoors, exclusively, the weather may limit your activity.
