Please teach yourself how long it is effective.
First of all, to get effective fitness training, different people are needed. Everyone's physique is different, and people with different constitutions have different ability to accept exercise intensity, so the time to show the effect is different, but most people are slow. It is possible to persist in exercising for a week, a month or two without obvious effect, but it is important to persist in exercising, and it will always be effective if you persist for a long time.
Is it necessary to take 50 private fitness classes?
Whether it is necessary to take 50 private fitness classes varies from person to person. If it is necessary for people who love fitness and can keep exercising, it is not necessary for people who don't like fitness very much and have poor self-control ability. Most friends who don't like fitness will be more or less xenophobic, and how many private fitness classes these people take is ineffective.
In the process of fitness, don't rely too much on personal trainers. Although fitness instructors can bring a lot of professional help, everyone's persistence and self-control ability are also indispensable. For example, in terms of diet, try to control eating less greasy food, or set a small goal for yourself every day, which is very helpful to the fitness effect.
