Question

It's no surprise that exercise increases energy. The physical challenge prepares your body in a variety of ways. Blood sugar is more quickly converted to fuel, more oxygen is supplied to your cells, and fight-or-flight hormones are released. Instead of leaving you exhausted, exercise energizes. Do it in the morning for an all-day high or later in the afternoon for a pick-me-up.
