The first time you go, you can get familiar with the environment and equipment without invitation, but if you don't invite in the future, you have to make strict professional plans and strong willpower on your own.

It is also hard to pull. Mastering methods and mastering methods are completely different. If the force is wrong, it is easy to hurt yourself. I've had enough. So if you don't want to hire a coach, you should ask more questions, how to use this and that, search the system's weight loss and fitness methods, make a detailed list, and stick to this plan every day or at least every other day. The important thing is to persist and challenge your limits!

Finally, I wish you success.
