An impromptu naked aerobics session took place as three men and a woman stripped off in the snow.
They braved the cold of the the Russian winter to stage the stunt on a city centre traffic island as shocked motorists drove by.
An eyewitness with a smartphone filmed them alternately jumping into the air and then getting down on the snow-covered ground to perform press-ups.
The bizarre incident happened in the city of Yuzhno-Sakhalinsk on Sakhalin island off the coast of far eastern Russia.
Bemused passersby can be seen standing and watching the four who have taken off all of their clothes and are wearing only shoes and socks.
