I can't. Foam brick walls are mainly composed of foam concrete blocks. Although the density of these blocks is relatively high, they are actually much lighter than traditional bricks or stones. Therefore, when the wall is not thick enough and the strength is not enough, hanging the horizontal bar and other fitness equipment will cause greater pressure on the wall and lead to the damage of the foam brick wall. In addition, hanging the horizontal bar will vibrate repeatedly, and some connection points and places with low strength of foam brick walls will be damaged by vibration. When choosing to install fitness equipment, it is necessary to consider the bearing capacity and strength of the wall, and try to choose some walls that can bear heavy pressure evenly, while foam bricks are not suitable for hanging horizontal bars.
