Laurence Llewelyn-Bowen has joked he will have to "up his medication" to be fit enough for the 'Changing Rooms' reboot.
The 56-year-old TV presenter is joining the upcoming Channel 4 revival as the oldest person on set "by about 20 years", and the star suggested he will need to "hit the gym" to keep up with his co-stars.
He told the Metro newspaper: "There was a moment when I felt it should be about someone new. Then you just go, 'F*** it! It always was so much fun. Why would I not?'
"But I am the oldest person on set by about 20 years and the first time round I'd be exhausted after three days. How I'm going to do six programmes and squeeze into leather trousers every day - I'm just going to have to up my medication and hit the gym."
Laurence will be joined by designers Jordan Cluroe and Russell Whitehead, as well as host Anna Richardson for the reboot of the popular 90s lifestyle show, which originally ran from 1996 to 2004.
While the interiors king revealed some of his previous designs from the initial series weren't that sturdy, his creations in the new series could survive a "nuclear explosion".
He added: "You'll see some of the most out-there designs I've ever done. And this time we're building them well. I do freely admit that in the first few series, my tarts' boudoirs divided the nation and a few were like a 'Crossroads' set, you couldn't really lean on them.
"Now they're indestructible so my only advice for anyone taking part is that they better like them because they'll survive a nuclear explosion."
Laurence previously admitted he believes the show will help to reboot the economy.
He said: "We went into lockdown obsessed with our beige, cookie cutter rooms that were going to look great in an estate agent window. We came out of it thinking, 'I don’t want to see another beige room for as long as I can live.'
"If you put yourself up a nice wallpaper with plenty of swirling birds and monkeys, palm trees, and tropical flowers, you are in the middle of a storybook."
