As for whether the private teacher can make a scientific fitness plan for you and help you achieve your fitness goals, it varies from person to person. At present, the professional level of private education is uneven, and coaches with responsibility and professional experience are not easy to touch.
So you don't have to ask a private teacher, but you should take the initiative to learn your own fitness knowledge.
In addition, the effect of losing weight through scientific exercise and improving living habits will not rebound easily. I have friends who have seen obvious results in two months, and have always maintained the habit of exercising, which is a very good thing.
