After making sure the rope is tightly attached to her harness, Lisa Cheng performs stunts as she makes her way up the wall.
At one point, she holds on to a big boulder with one hand, and swings her body in the air, soaking up the experience.
'Many people say climbing is risky. Actually this is not the case. We focus more on safety rather than technique. It also gives you great satisfaction when you make it to the top,' says Cheng, a professional climber.
Sports climbing has caught on in Hong Kong in recent years, and Cheng is aware of its increasing popularity.
The champion at both the UIAA Climbing World Cup 2006 - Shanghai and UIAA Asian Championships 2006 - Kaoshiung has been in the sport for 10 years after first trying it as a 12-year-old.
'A lot of young people are giving it a try. The government and sports centres are also offering support by organising various climbing courses. There are more than 20 sports climbing areas in Hong Kong now,' she says.
There is a major difference between sports climbing and rock climbing (also known as traditional climbing).
