Walking vs. stationary bike

"Exercise expert Dr. Kenneth Cooper ranks walking and stationary bicycling as two of the six best exercises. He writes that walking is particularly good for previously sedentary people and older people. He recommends stationary bicycling because it simultaneously strengthens bicyclists’ arms and legs and causes far fewer injuries than jogging and outdoors bicycling. The Merck Manual Home Health Handbook’s “Choosing the Right Exercise” report lists 10 exercises, including stat...ionary bicycling and walking. Walking is praised for being “relatively easy” on joints throughout the body and being better than stationary bicycling for people with knee problems. Stationary bicycling improves strength more than walking and lets people change the intensity of their workouts by changing the bicycle’s resistance." Walking is almost out of the question for me except for brief errands. That's why I just love my stationary bike, a power spin 210. http://healthyliving.azcentral.com/stationary-bicycle-vs-walking-exercise-9889.html
