As long as you have plenty of money, it is necessary for you to hire a tutor. Otherwise, first of all, it is easy to get hurt if you practice by yourself, because if you don't get the guidance of the coach, your movements will be very nonstandard. Second, irregular exercise will not be effective, and white exercise will also hurt your sports mood. Third, not only the exercise needs the guidance of the coach, but also the daily diet plan should be arranged by the coach. You should know that training without eating is just consumption, and you can never keep your muscles and fat. You can only eat but not practice. To be fat, you have to eat and build a muscular man. So the training method and eating method depend on the coach to help you do it. Therefore, novices must have a coach to take you to practice, and it is best to invite a personal trainer for one or two years. Then when you have the experience and knowledge of exercise, you can ask the coach to make a plan for yourself to eat and practice.
