Fitness walking is called by many different names - power walking, fitness walking, health walking. Power walking is commonly used to represent an exaggerated walking style. This style of overstriding and exaggerated arm movements is often linked with injuries. Because of this I don't generally use the term power walking. A better term for a healthful energetic walking pace is "fitness walking".
Fitness walking is much more than a stroll or nature walk. When fitness walking you incorporate the muscles of the upper body making it a GREAT aerobic activity. It burns approximately the same calories as running, yet it is much easier on the body. Because more muscles are used it burns calories much quicker than less aggressive walking. It also tones muscles in the buttocks, thighs, hips, shoulders, upper back and abs. Most fitness walkers average about 12 to 15 minutes per mile.
Unlike racewalking; there is no official definition. There are no rules. If you walk at a purposeful fitness walking pace using good technique you are a fitness walker. Use tips above to insure good walking form and to increase your pace.
