The maraca-shaking dancer, famed for his onstage antics as part of the Madchester-era band, hopes to lose his lockdown weight and help motivate others.
But unlike fitness coach Wicks, Bez will be following the orders of a personal trainer as well as visiting a psychologist, learning yoga and trying hypnotherapy.
He said: “I’d like to think I’m somewhere between Joe Wicks and Mr Motivator.
“I’ve started this new year seriously unfit, with a fat belly and creaky hips, and I can’t stop eating chocolate.
“Last lockdown I got unfit, fat, lazy and into some seriously bad eating habits.
“This year, this lockdown, I need to sort it out sharpish.”
A short teaser video shows Bez warming up in a park under the watch of a personal trainer from the Fit Forward company.
Happy Mondays, fronted by Shaun Ryder, was one of the leading bands in the Madchester scene of the late 80s and early 90s, with songs including Lazyitis, Step On and 24 Hour Party People.
Fitness coach Wicks became a lockdown hit when he launched his online fitness classes which were watched by more than 1 million people around the world.
