may have sporty parents, but his father sees only one game in his 4-month-old son's immediate future.
"I think the only sport he will be good at is playing tiddlywinks," Prince William
joked to Ryan Gordon on Wednesday.
Gordon, 18, was among a group of budding sports coaches with whom William visited at Coach Core
, a training and apprentice coach development program established by the prince, wife Kate
and brother Prince Harry
for 16- to 23-year-olds living in London's most disadvantaged communities.
Wearing a blue sweater and slacks, William, 31, exhibited his volleyball skills and participated in drills at the Westway Sports Centre in west London, and even got an offer to improve them from one of the young coaches-to-be.
"I could offer him that help," said 18-year-old Terrell Jordan from Battersea, south London.
Coach Core was set up in July 2012 by the Royal Foundation
of the Duke and Duchess of Cambridge and Prince Harry.
There are two pilot programs, in London and Glasgow, as well as a sister project in Harlem, which Prince Harry visited earlier this year.
"They want to get to know what we are doing and how we can improve," said Robert Salteres, 25, who met William Wednesday, several months after meeting Harry.
Salteres, who hopes to be a baseball strength and conditioning coach in New York, said the initiative was also about creating job-orientated skills to aid employment hopes.
"It's great for creating a positive cycle for youth who come through it," he told PEOPLE.
While in London, Coach Core visitors visited the Tower of London and had a private tour of the public areas of Kensington Palace, where William and Kate just happen to live. They didn’t hear any cries from baby Prince George, but they did catch up on some history.
Salteres told PEOPLE, "We joked with the prince about how old everything was and how the buildings were older than our country and he said, 'Yes, you have nothing as old as that!' "
