Second, make a plan: write down the exercise you need to do every day on a piece of paper. It also includes what to eat every day and strictly control calorie intake. Then follow your own plan every day.
Third, persistence: I made a plan, but I didn't stick to it. Two days of fishing and three days of drying nets. It's useless. This way, even if you exercise, you will rebound if you don't insist.
Fourth, verification: I will measure my weight once a week or half a month. If you know what you are doing, you can change your plan according to the effect at that time.
