Parkour practitioners use various techniques—including climbing, rolling and leaping—to scale obstacles that are in their path. Parkour members train in close teams, and teach each other the skills to overcome individual areas of weakness. The Hong Kong Parkour Association (HKPA) is the official parkour group in Hong Kong. There are free training sessions at Kwok Shui Road Park in Tsuen Wan every Tuesday at 7:30pm. Small group sessions are also held on Saturdays to allow members to develop specific skills.
