When Is The Best Time Of Day To Exercise

Not sure whether you should workout in the morning, noon or night to maximize your fitness and weight loss? Studies show that exercise at night provides less optimal training of your body. The latest survey on metabolism in the United States involves the study of muscle tissue of mice. They came to the discovery that rodents have all day long “clocks” in the muscle tissues. Those “clocks” control metabolic reactions and energy in the body, based on the time of day.

The final result claims that muscle cells are more efficient in the period after getting up from sleep, in a time frame of a few hours.

Mice, that are nocturnal creatures, were placed on special wheels for exercise immediately after daylight, and scientists noticed that their muscles were more effective at adapting the movement, using oxygen as an energy “fuel” that should not be wasted as sugars and fats. Apart from this easy exercise, at night, the muscles of mice activated genes that help them adapt to exercise.


Since humans have the same genes, the researchers believe that people show a better results in their morning workout. That time we are biologically programmed to be more sober and awake. The exercise will be accomplished with less effort and is more natural and brings better results.

Remember this – Everybody’s Different! All people have different preferences and predispositions regarding their response to exercise at different times of the day.

The American Heart Association recommends at least 150 minutes (2 hours and 30 minutes) a week of moderate-intensity, or 75 minutes (1 hour and 15 minutes) a week of vigorous-intensity aerobic physical activity. But what if you’re tight on time? Then, be creative and break up your activity into daily bouts of 3 to 10 minute increments.

For example: In the morning, park 5 to 10 minutes away from the job and walk briskly. At lunch, walk 10 minutes in or around where you work. In the afternoon or evening, walk briskly 10 minutes back to your vehicle.
