Now the personal trainer fees in Beijing range from 150 ~ 300 (mostly), so what you said is normal! But it is your freedom to buy or not, because members may not have a coach to practice well when they come to the club. If you have enough perseverance and professional fitness knowledge, you don't need a coach, but if not, you can consider buying how many coaching classes. Generally, a gym's three-month training plan of 24-25 sessions will recommend 8 sessions/month, but you can also buy 12 sessions, with lower discount and fewer gifts, but because I am in the industry, I also heard that his family is going to raise prices (probably true), but I don't know when.
