 What Is the Best Time to Exercise for Energy?

Energy levels ebb and flow throughout the day, influenced by everything from your mood to your body's circadian rhythms—daily fluctuations in things like heart rate, temperature, and blood pressure. Here are the pros and cons of exercising at various times of day.

MORNING: The main hurdle in the morning is dragging yourself out of bed. Once you've done that, however, there's little else to distract you from the bus­iness at hand. That may be why people who work out in the a. m. are more likely to stick with it over time, which means they're well on their way to reaping the long term energy boost that being fit brings.

LUNCHTIME: Most people feel an energy dip be­tween two and three in the afternoon. It's not related to eating; it's just part of the body's natural cycle. Exer­cising in the middle of the day can smooth out the dip, because it increases the flow of epinephrine and norepinephrine — hormones that perk you up for a few hours after a session. But don't skip lunch to work out. A light meal an hour before you exercise will give you the energy to get moving.

EVENING: In the late afternoon and early eve­ning, people breathe easier because the lungs' airways are more open, muscle strength peaks since body temperature is higher. But, don't work out too close to bedtime for the resulting burst of vigor may make it dif­ficult to fall asleep.
