It doesn't matter In fact, as long as you persist and exercise properly, it will be effective. Even it is good to spend half an hour doing push-ups and sit-ups before going to bed every day.

If you want to exercise at night, the time should be 45 minutes or an hour after dinner. Whether it is aerobic exercise or equipment exercise, if it is aerobic exercise, it is just like running. You must be prepared before running, especially in winter. You'd better jog if you want to lose weight. Running for 30 to 45 minutes is almost enough. Be sure to keep warm after exercise. You can eat some fruit and drink some milk within two hours of fitness. You need to replenish water before, during and after exercise. Finally, it is best to take a warm bath after fitness at night, which can relieve the fatigue of the next day.
