Kwik Fit's New Kent Road branch has launched a new fitness class using old car and van tyres.
The free 30-minute sessions will include tyre flips, lifts and throws, during which participants should burn up to 1,200 calories.
The fitness classes are being trialled at Kwik Fit's New Kent Road centre on four Sunday mornings throughout January and if successful they will be rolled out nationwide for all Kwik Fit customers.
Personal Trainer Mikah Simpson said: "There's no doubt tyres are a brilliant foundation to a work-out – not only for lifting, but on the floor during cardio exercises.
"The most important thing when getting fit is to simply get started and do something you enjoy. We promise to create a fun atmosphere and leave participants feeling that they've done something worthwhile."
Kiwi Fit's Paul Boulton said: "We think everyone is exhausted by faddy diet plans and complicated exercise regimes.
"We want to put the fun back into fitness for the everyday person with a no-nonsense class that doesn't take itself too seriously.
"Our stripped down class consists of just you and a few tyres in one of our centre car parks. The trial of our new 'Fit Kwik' class this January is open to anyone who wants to shift that post-Christmas spare tyre – with our spare tyres."
