Excellent for the heart and lungs and is one of the best aerobic activities. It can even save you money getting around while it’s builds cardiovascular fitness. It is also low impact which means it doesn’t damage bones. It also helps with osteoporosis, particularly if you strap on arm weights. Fast walking burns around 275 calories an hour and strengthens hips, thighs, stomach and bottom muscles. Adding arm weights as you stride will build up arms and shoulders. It should be combined with a form of stretching exercise such as yoga or Pilates, for total fitness. (Specific calf and thigh stretches are also recommended pre-and post-walking workout, to stave off strains.) A vigorous walk, during times of stress, can be more effective than tranquillisers.
