PRAGUE, Dec 12 — A Prague gallery wants to challenge the belief that the gym is the place to go to tune out of life’s problems.

At the "Hard Times” gym exhibition in the Dox Gallery, visitors can exercise but as they do art installations confront them with some of the world’s most troubling issues and allow them to vent their frustrations.

In the installation "My Love Answer Me” by Israeli artist Elinor Milchan, treadmills face a large projection of footage from places prior to terror attacks, including the 2013 Boston marathon, when two bombs killed three people and injured more than 260.

Nearby, a sculpture is made of tiers of water bottles bearing the names of diseases faced by those with no access to clean water such as typhus, diphtheria and hepatitis.

In "Left or Right”, an exhibit by Cuban-American artist Antuan Rodriguez, visitors can thump large punch bags bearing the images of world leaders such as US President Donald Trump or Russian President Vladimir Putin.

"Visitors will have the opportunity to sweat out their obliviousness and train their conscience,” curator Erik Kessels said. "After the workout they will feel invigorated, informed and perhaps even a little more aware of what is going on in the world.” — Reuters
