A woman who endures the freezing cold to swim in one of Europe's coldest rivers says her unusual fitness regime keeps her looking young and healthy.

Inna Vladimirskaya strips off on the banks of the Dniper river in Kiev, Ukraine every Sunday morning.

She also runs along the snowy banks - a ritual she has been doing for the past nine years.

The 32-year-old says walruses look younger than they really are, because they spend so much time in cold water, and wants to emulate them.

Her swim was captured on camera by Czech photographer David Tensinsky - who had heard of her 'crazy' ritual from locals who see her skinny dipping every weekend.

Inna said: "Every week I take a run in the snow and then plunge into the water.

"Immersion in cold water makes the blood rush to the internal organs, activating their circulation, which helps break down fat and improve muscle tone.

"It also helps beat muscle and joint pain and rejuvenates my skin, because of the increase in oxygen supply to it.

"The walrus looks much younger than its actual age, because it spends so much time in cold water - humans can reap the same benefits if they are prepared to put the hard work in.

"I just make sure I don't stay in the water too long, and as soon as I am out I dry myself and go straight to my warm car."
