Walking is not the most exciting form of exercise a person can take on for fitness. Yet it is low impact and requires no fancy equipment. That makes walking a simple activity for those new to exercise. Walking is less likely than other exercises to cause injury to leg tendons and muscles. All it requires is a good pair of sneakers - no cables , stylish outfits , or weights required. Of course , a person could increase the benefit of a workout by adding weights or speed walking.
