Walking is a low-impact way to ease into fitness. Walking tones muscles in the legs and abdomen, thus supporting joints. As a weight-bearing exercise, it builds strong bones which help prevent osteoporosis. If you are new to walking, start out slowly walking five to ten minutes a day. The greatest benefits come from 30 minutes of brisk walking five times a week. Research shows this can be broken up into two 15-minute or three 10-minute increments. Be sure you have the right shoes. Look for shoes specifically made for walking vs running or cross training. Shoes specifically made for walking stabilize your feet and absorb shock. Proper fit is a key: snug but not tight with room to move your toes easily in the toe box.
