Spray wall

A spray wall is an overhanging climbing wall almost fully covered by a great variety of different sizes and shapes of climbing holds, in apparent chaotic distribution.^[1] It is used to train power, endurance and routesetting.^{[2][3][4][5][6][7][8]}

According to Noah Walker, author at Gripped Magazine, one of the main differences between a spray wall and a standard climbing board is that spray wall's greater hold density force climbers to develop their own problems;^[9] in particular, he states that the large grips (more frequent on spray walls than in standard boards) force to use similar three-dimensional movements and precarious heel hooks that are necessary for climbing natural walls;^[9] he insists that on a spray wall, a climber can't become as easily used to the distances between holds as with a Moon, Tension, or Kilter board.^[9]

Exercise training researchers stated that spray walls help to develop routesetting skills more than standardised training walls, because they force climbers to observe, memorize, and mimick the problem-solving strategies and motor actions of other climbers as in outdoor climbing.^[10]

Professional rock climber Adam Ondra considers it a better tool to develop physical strength for climbers than campus boards or pull-ups.^[1]
