There's a seemingly never-ending list of studies about the ideal exercise time. But Chris Jordan, exercise physiologist and creator of the viral seven-minute workout, would argue that choosing when to pencil in your workout is ultimately a personal decision. "The best time of day to work out is the time you're most likely to work out," he told Business Insider. In other words, you won't reap any of the health benefits if you don't make it to the gym.
Jordan, who worked as a fitness consultant for the European branch of the U.S. Air Force before becoming the director of exercise physiology at the Johnson & Johnson Human Performance Institute, experimented with many different workout times before settling on an afternoon gym session. "What I like about working out in the afternoon is that I'm loose, I'm not typically as tired, and my muscles aren't stiff like they sometimes are in the morning. Plus, it's a great break, and I get so much energy afterward."
With that said, he does admit that working out in the morning can help boost energy and metabolism, aid weight loss, and help your body burn fat, so if you're a morning person, take advantage of it. "Maybe you're a bit sluggish in the morning, but if you choose that time, then at least it's done for the day, and you're not going to skip it when unexpected things come up," he adds. "The most important thing is to do it on a consistent basis."
