Working mom

Huang Hui, 38, chooses to visit the gym late at night because her evenings are devoted to looking after her young son.

"I go to the gym around 11 pm four times a week when my son is in bed. Since I became a mother, most of my spare time is spent looking after my child, so I didn't think I had much time to work out," the working mother said.

However, encouraged by her husband who regularly visits fitness centers, Huang started working out at a 24-hour gym.

Although she only started about four months ago, after Spring Festival, she has already lost more than 10 kilograms.

Smaller gyms can greatly improve people's athletic abilities, as the coaches have more time for each member and can offer advice, according to Huang.

A traditional gym may be more suitable for people who have already formed fitness habits, have a certain level of experience and know how to use the facilities, but smaller classes are ideal for newcomers or those who need inspiration and instruction, she said.

"The exercise has helped me become more energetic at work," she added. "I have formed healthier eating habits and my skin condition has also improved a lot."
