Unissued / unused footage - dates and locations may be unclear / unknown.
Various shots of new form of hinged slimming / exercise beds which, due to their hinge and pivot positions, move all parts of the body for the minimum of movement by the person on the bed.
It looks really funny - some people are frantically moving up and down on their beds (they look like z-beds or sun loungers), while others are making small movements and looking a bit doubtful. Some are enjoying the experience immensely! 'Let's Twist Again' by Chubby Checker is on the soundtrack.
Final shots show everyone lying down asleep or resting on their slimming beds.
This is a good one! Very funny!
