Secondly, the intensity control during exercise, usually reflected by heart rate, is very important for reducing fat. It is best to control the heart rate during exercise in the range of 50%~75% of the maximum heart rate (220 years old) for fat reduction. This is the biggest problem. Your fat-reducing effect is not good.
The second is the frequency and time of exercise. In general, it is recommended to exercise at least 5 times a week, preferably once a day. 50~60 minutes each time is the best. You keep exercising for two hours every day and haven't lost a pound, which shows that your exercise intensity is not enough.
I suggest you run outdoors at 2~3 pm. If you don't want to run, you can do aerobic exercise at home. For example, P90X (available on major video websites) has higher strength and better fat-reducing effect.
