Hello. Gyms are generally charged according to annual cards and season cards. The monthly card is more expensive than the last two.

The annual cards of the better gyms in big cities are all around 3000~5000.

Jika 1500~2000 or so

The monthly card is also about 600~800.

If it's a small gym. The monthly card is around 3-400.

I hope I can help you and adopt it.
