Thirteen-year-old Harrison's weight loss mission

Teenager Harrison Wright spends more time in the gym than many adults.

The 13-year-old, from the Black Country, began trying to improve his health two years ago, when he was told he was overweight.

Harrison attends the gym twice a week with his mum, Kerry, where they work out together with a personal trainer.

He says that, through social media, he has been able to inspire other young people to take better care of their health.
