The Kremlin has released pictures of Vladimir Putin and his Prime Minister Dmitry Medvedev pumping iron together, in a bizarre attempt at bulking up their popularity by boosting their image as masculine and rugged.

The pictures show the pair in sweatpants and T-shirts operating various pieces of gym machinery before enjoying grilled meat and tea together.

The publicity shots, which are reminiscent of when Putin has himself pictured shirtless on a horse, flying a supersonic jet and hunting a tiger, have appeared at a time when the President’s public approval has been dipping.
