A chartered surveyor turned entrepreneur has used a childhood pastime to develop a fitness product which has been tipped for big things.

Tim Worboys, who is originally from Harpenden, has swapped 25 years in the building industry to focus on his creation, WallJAM - an interactive rebound wall which helps keep people fit.

The wall which connects with an app on a users phone allows players and coaches instant access to the kind of performance data that would have been unheard of a short while ago.

Mr Worboys, who now lives in Kimpton, said: "As a kid, I could have easily failed as an academic but sport helped me to focus and succeed in all areas of my school work.

"Unbeknown to me, the hours spent playing with a ball and a wall built the foundation and set the pathway of my success in adult life. I have no doubt I am not alone in this regard and these same experiences will apply to a vast number of young students trying to find their feet academically."

The 50-year-old added: "I love the fact I am able to apply my in-built passion for sport and health to a business that I genuinely believe can make a difference to people’s lives."

WallJAM has been shortlisted in The Daily Telegraph Sports Technology Awards in the Most Promising Concept category.
