Local teenagers are lagging far behind their counterparts in other developed Asian nations when it comes to physical activity, according to Lobo Louie Hung-tak.
Dr Louie is an associate professor of the department of physical education at Hong Kong Baptist University.
He said there was a lack of focus on physical education in Hong Kong.
A study has found that local teenage boys were able to do fewer than four pull-ups on average compared to between eight and 10 pull-ups by youngsters in Japan, South Korea and Singapore, he said.
With inactivity leading to rising obesity rates around the world, Dr Louie said those aged eight to 18 should focus on training their bodies to ensure lifelong health.
Young Post agrees with Dr Louie. Exercise can help enhance your physical fitness and overall health. It boosts your immune system and prevents disease.
