If it is before 8 o'clock in the morning, you can choose aerobic exercise such as running for about 30 minutes, then go home for breakfast and eat boiled eggs and fruits. Or you can add some anaerobic exercise before breakfast, such as four groups of belly rolling, four groups of sit-ups and four groups of flat support. Try not to exercise too much in the morning, and try to exercise with your own weight.
If it is around 10, it is not suitable for exercise at this time, but the process of building muscle and reducing fat is generally aerobic first and then anaerobic. If you have any other questions, please feel free to contact me!
