Working out has major health and stress-relief benefits. But what is happening head to toe? “When your body breaks down energy-dense foods, like carbs and fats, it turns them into the molecule adenosine triphosphate (ATP). Then, when the body converts ATP into adenosine diphosphate (ADP), it gives off energy and allows muscles to contract and move. It’s what we mean when we say we’re ‘burning calories’,” said Joseph Herrera, DO, system chair of rehabilitation medicine and professor of rehabilitation medicine at the Icahn School of Medicine at Mount Sinai. As your body burns calories, its temperature rises, and you sweat. “Sweat wicks away heat, which allows your body to keep working out without overheating.” Each time a muscle is challenged, micro tears occur, but they aren’t harmful; they contribute to muscle growth over time.
