Jack, who joined the MTV reality show in February, has teamed up with fashion brand Big Boss to bring out a collection of wearable gym clothes.
The Welsh reality star, who aims to become a bodybuilder like Big Reunion's Kenzie or Jodie Marsh, has personalised his range with a grizzly bear.
Jack tells Reveal: "I'm a regular gym goer myself and I wanted to bring out a range of clothing that was both practical for the gym, but also wearable out and about.
"My collection with Big Boss ticks both boxes and is also personalised by me with the bear logo."
One item in his collection is the Beast stringer vest - and this is something Jack says he can relate to!
"When I go into the gym I do turn into a bit of a 'Beast' and my ambition is to get bigger and bigger," Jack adds.
"I might even 'do' a Kenzie or Jodie Marsh and go down the route of bodybuilding in the future."
