Shiver-Based Muscle Toning
From the essay
First – an obvious contradiction. Common knowledge suggests that to tone up and strengthen your muscles one is expected to engage in vigorous exercises over long sessions. Vigorous exercising involves spending significant amount of energy and burning lots of calories … and time. However, the human body is designed in such a way that it performs physical work (and vigorous exercise) in the most economic manner: it saves energy by optimizing its use.
