I am a student, too. I'll tell you a good way to have a cup of black coffee before jumping. Black coffee without sugar will help you burn fat. Drinking it will make you sweat more than usual. I just dance two sets of little red riding hood and two sets of gray hats every day after drinking. I lost 4 pounds a week, but I suggest drinking coffee 30 minutes after lunch and dancing at night. Don't drink coffee if you want to dance at night, or you will not be able to sleep. Duoyan Zheng's exercises are only effective after jumping. Don't overeat when you are happy.
It's normal for you to be sore for a long time at the first jump, so you can do it easily. After getting used to it, you will sweat less, so it is not so difficult to suggest strengthening it.
Give me some. Give me points ~ ~ ~
