Muscle-training equipment, such as the chin-up bar, can be placed on a tougher surface than commercial playground equipment. The surface may be entirely hard up to a free fall height of one meter. A free height of fall on a lawn or topsoil is permitted. The impact zones may overlap since fitness equipment does not generally entail forced motions.
Park equipment such as monkey bars, rock walls, and wooden swing sets may be built on a totally solid floor up to a free height of fall of 161 cm when a gymnastic area is meant purely for training and not for play and is positioned away from any playground. With higher fall height tube slides, the shock absorption capability must be two-thirds of the item's free fall height. A 241-centimeter structure, for example, might be erected on a surface with a critical free height of fall of only 161 centimeters in the playsets.
