Bicycling / walking are lifelong activities that do not involve a steep learning curve and are relatively inexpensive to maintain.
Both walking and bicycling can produce a number of positive health benefits including:
Improved cardiovascular fitness
> Physical activity strengthens the heart, which improves blood circulation and reduces blood fat levels and resting pulse.
> Riding as little as 30 minutes every other day meets the American Heart Association’s recommendations for a healthy heart.
> Exercise such as brisk walking for 3 hours a week — or just half an hour a day — is associated with a 30% to 40% lower risk of heart disease in women (Based on the 20-year Nurses’ Health Study of 72,000 female nurses)
Increased joint movement and less pounding
> Cycling reduces the risk of arthritis (or inflammation of the joints) caused by worn out cartilage.
> Cycling is gentler on joints and can actually strengthen them because the cycling motion provides nourishment that builds up cartilage.
Stronger immune system
> Moderate exercise causes a boost in the immune system by increasing the production of cells that attack bacteria.
Weight loss and fitness
> Exercise, like cycling and walking, burns calories, raises the metabolic rate, and builds muscle tone, so you burn more calories while at rest.
Stress Reduction
> Exercise in general has been shown to decrease anxiety and stress levels, and bicycling and walking can be fun ways to exercise.
> Keeping yourself out of traffic jams will also help in reducing stress.
