Move over monkey bars, these polygonal bouldering blocks are the playground equipment of the future.
Hard Body Hang (HBH) out of Budapest, Hungary has created decahedron and tetrahedron “Urban Boulders” to help more people enjoy the thrills of climbing, outdoors and for free, while in the city.
In an increasingly urbanized world, not everyone can skip town to get to real rock. Today, 55% of the world’s population live in cities, a proportion that is expected to increase to 68% by 2050 based on predictions by the United Nations.
Accordingly for urbanites, the sport of climbing is growing fueled by indoor facilities.
In the U.S. there are over 7.7 million climbers, according to an Outdoor Industry Association report from 2014, with over five million frequenting the gym, as noted in the 2019 State of Climbing report by the American Alpine Club. The Climbing Business Journal tracks the commercial gym industry and their research shows about a 6% yearly growth rate for new climbing gyms since 2000. Based off data from the Climbing Wall Association, gym facilities average over 100 new members per month.
That’s a lot of people flocking indoors, which HBH is trying to change.
As former rowers, Szabolcs Csepregi and Tamás Erdélyi spent much of their career training inside. When they retired, they began looking for a way to stay fit alfresco; Ideally cheaply and always accessible. That’s when they came across body-weight exercises in city parks.
“We started making street workout equipment six years ago [think pull-up bars, monkey bars, parallel bars],” says Mezős Balázs, the Marketing Director of the company. “Our motto is ‘playground for all,’ because the important thing is that these are sports for anyone—You don’t need any extra equipment. Anyone can go and start working out and having fun.”
HBH gained in popularity as the parkour and street workout movement grew across Europe. Parkour is like American Ninja Warrior in a metro setting, emphasizing dynamic movements—such as swinging, stemming, and jumping—to navigate through complex environments and structures typically found in city parks, subway stations, and stairwells. Part of the allure of the activity is the freedom it allows participants to reimagine the concrete jungle.
Since 2013, the company has installed over 300 workout parks from Segovia to Hong Kong and Abu Dhabi to Ruka.
Bouldering parallels parkour for its potential accessibility. After all, you only need shoes and something to climb as a baseline. However, crags are often far from downtown and inaccessible by public transport, while gyms are expensive.
Bernard Gara, one of the newest members of the team, joined with 20 years of climbing experience and encouraged the group to think about new types of equipment for public spaces. They began designing ways to make bouldering available for any inhabitant of a city.
Thus, the Zigzag boulders were born.
Made from hot-dip galvanized steel and weather-proof materials, the modules provide a fully customizable human-sized puzzle. And if the blocks remind you of the maddening Rubik’s Cube, that’s because they were inspired by the 3-D combination game, which is, *ahem*, another Hungarian invention. (Thanks, Ernő!).
“Today, in Hungary, people rarely go rock climbing,” begins Mezős. “They climb indoors and that’s why I think it’s important to show them how much better it is go to outside.” Even if it’s in the city.
