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.
