A young polar bear cub becomes the yogi bear as she stretches off for a morning aerobics session. The amusing pictures show her appearing to stretch her hamstring and extend her leg upwards as what could be part of a gym routine. She then turns on her back and stretches the same leg as if she is preparing for a big burnout or peaceful yoga session. But the five-month-old young cub then takes to the water's edge and contemplates a dip in a nearby pool. Minutes later though she decides it is all too much like hard work and opts for a cosy up and a sleep with her mum Simka. The shots were taken by Russian photographer Olga Gladysheva at Moscow Zoo last month
