Even if you don't sign up for a fitness class, you can lose weight successfully as long as you have perseverance and perseverance. Many people who report to work around you spend three days fishing and two days drying their nets. Because of one reason or another, they will all go away in the end.
Of course, going to a special environment may make you more self-disciplined to some extent. And get some formal training.
It depends on personal choice. If the distance from the gym is moderate, not too far, and the cost is reasonable, it is not bad to apply for one.
But you should study hard before you sign up for class, because some gyms don't know when to close and don't even say hello.
