First of all, if you are obese, I personally suggest that you find a personal trainer to talk about your weight quickly, because the personal trainer will make a weight loss plan and weight loss goal for you according to your actual situation, and all kinds of equipment and movements will help you complete it in a standardized way without wasting your time and energy. This is the most important thing! When you can use all kinds of equipment, you don't need to find a private teacher. Save it if you can. After all, private education is still very expensive!
Secondly, if you are not very fat! You don't need a private tutor, you just need to ask the coach how to do all kinds of instruments and movements and how to do them. You don't need to ask for private education, which saves unnecessary expenses!
Finally, and most importantly, it is persistence. This is the hardest, so you have to be tough. Only in this way can you lose weight successfully. You'd better find a friend to go with. Two people can encourage each other. If you are alone, it is easy to be lazy and encourage each other! Finally, you can have confidence. You have to believe that there is a difference before people, and there is suffering after people!
I hope you are satisfied with my answer, and I wish you and your family a happy New Year and good health!
