A study by researchers from the University of Northwestern in Chicago, America, that the body's response to exercise varies with different times of the day, and the optimal time is in the light of the day, where the ability to perform in most people the most.

The study, attributed by the German agency "Deutsche Welle", to certain proteins that maintain the stability of the process of metabolism within the body when oxygen levels in muscle cells low during exercise. These proteins are when one is very awake. Researchers recommend that you use the lunch break to go to the gym.

Despite this recommendation, it is often difficult to determine the ideal time for exercise. It also varies from person to person and is also related to the type and purpose of the exercises. That's why you don't always have to exercise before sunset.

Anyone who goes to workout in the morning can get more energy, higher levels of testosterone, higher metabolism, and better sleep.

Exercise in the evening has more strength and less tension.
