Researchers discovered: when sportsmen just watch someone exercising their muscles act in the same way if they were exercising themselves. Thus, fitness spectacles with a choice of fitness video programs can help people build a great and healthy body without actual excercising. Fitness spectacles would be a valuable product not for lazy or sick persons only. They would also help travellers, people waiting for something and other to make the most of the time otherwise waisted.
