Spin bikes will be swapped for single beds at David Lloyd gyms in a new "Napercise" fitness class.
The session consists of nothing more than climbing into bed and having a sleep.
Napercise aims to provide exhausted parents with 45 minutes of much-needed sleep.
According to David Lloyd, the sleep sessions have been scientifically designed to reinvigorate the mind, improve moods and even burn the odd calorie.
"Here at David Lloyd Clubs, we’re always looking for new ways to tackle the issues that everyday families face, which is what ‘Napercise’ sets out to do," a David Lloyd spokesman said.
"Filling an exercise studio with beds might look unusual, but if it proves to be a success, we’re definitely excited at the possibility of rolling out the programme to more of our clubs down the line.”
Upon arrival guests will find plush single beds and hear atmospheric sounds softly playing in the background.
The studio temperature will also be dropped to a level that promotes calorie burning during sleep.
Napercisers will be invited to curl up in one of the beds and indulge in some restorative mid-afternoon shuteye, before continuing on with their day.
The development of Napercise is inspired by past academic studies into the important health benefits that napping in the day can bring.
This includes helping boost alertness, alleviate feelings of anxiety or stress, and improving your mood.
Napercise is to be held at David Lloyd Sidcup over the weekend of Saturday April 29 and Sunday 30.

Depending on the success of the trial, David Lloyd Clubs will look into rolling the sessions out to more of its clubs across the UK.
