Aidan Heslop used to stack shelves – now he stands on them, peering down into water 90ft below before diving off a cliff.
The old shelves belonged to Morrisons supermarket where the 19-year-old used to load potatoes.
The new ones are shelves built into rock cliffs from where the best divers in the world launch themselves down into the blue waters of the Adriatic Sea.
Just like Olympic champion Tom Daley, who became the youngest winner of the senior British 10m title at the age of 16, Heslop has also shown his talent at an early age.
The Chelmsford-born athlete became the youngest diver to compete in the Red Bull Cliff Diving World Series four years ago. He made his debut in the 2018 season finale in Polignano a Mare in Italy.
Later this year, Heslop - who qualifies for Wales though his mother Helen - is set to compete for Wales for a second time at the Commonwealth Games in Birmingham.
Regular diving differs from the Red Bull cliff diving series, he says, but with a busy year ahead, the 19-year-old is determined to thrive in both.
“Red Bull diving is slightly different to diving, weirdly,” says Heslop.
“In normal diving, you kind of cheer for your team and stuff. It's got a real rivalry, whereas when it comes to high diving, it’s such a tightly packed group that everyone is like a little family.
“Everyone knows everyone, everyone wants to make sure that everyone else is okay, does well.
“So it’s just really pleasant to compete there. Every time I go to a competition, everyone cheers for me. It’s just a really nice atmosphere to be around when you’re there.”
The teenager was the first diver in 20 years to represent Wales at the 2018 Commonwealth Games on the Gold Coast.
That chance to make history in a red vest was all down to his mum - and a chance conversation at a party.
“It was a bit of an honour in a way. My mum is the Welsh side of my family, so she was extremely excited as well. She’s from Blaina, a tiny little town near Abergavenny.
“It was weird because we hadn’t even thought about it before until my coach mentioned it to my mum at a New Year’s party and she was like, ‘Why don’t we just get him to compete for Wales?
“My coach agreed and it turned out, the last guy, Rob Morgan was from 20 years ago. He was the last before me to dive for Wales.”
