In general, the morning period is better for training ... but people's conditions are different ... and each has his own personal routine ... and professional athletes exercise more than once a day ... according to specialists, training in the morning is better because the body's systems are ready for activity
Working out first thing in the morning, particularly on an empty stomach, is the most effective way to burn fat and is therefore perfect for weight loss. According to Anthony Hackney, a professor in the department of exercise and sport science at the University of North Carolina Chapel Hill, this is primarily due to the body's hormonal composition in the morning being set up to achieve that purpose.
The best time to go for exercise is early morning at 6 a.m.,however you can also make out time by 5 p.m. in the evening when the sun is down when you are back from work if you can't make it at morning.
