Because as successful people, when they need to deal with the most important thing in life or the thing they want to do most, the early morning is exactly the most self-controlled time in their schedule. Fitness exercise, it is best to arrange in the morning, because the work itself is very tense, and there are often various emergencies. As the deadline for work projects approaches, it is often necessary to work late, and the pre-planned fitness activities can never be completed. So people who really pay attention to fitness will put physical exercise in the morning.
