Hello, it is most appropriate for me to answer this question, because I used to be a fat man weighing more than 200 kilograms, and then I lost 150. Weight loss should be combined with aerobic and anaerobic. Simple aerobic exercise will consume your muscles and fat and make your skin more relaxed. Combined with anaerobic, it will increase your muscles and make your skin tight. Usually, you should warm up for ten minutes, then do anaerobic exercise, and finally do aerobic exercise for more than 20 minutes. The most obvious effect is to keep your heart rate between 60% and 75% of the highest heart rate.
