Exercise more. If you are busy at work, you can pay more attention to your usual time. For example, during working hours, you can take the stairs and take fewer elevators. If time and physical strength permit, you can walk or ride a bike instead of taking a bus or taxi. Most men are fat when you have time to do sit-ups. Usually you can do more aerobic exercise, such as race walking, morning running and running with your lover. This feeling is wonderful. Do some interesting sports and play ball several times a week. There is no need to go to the gym. Good luck, losing weight is a long-term solution.
