It's not entirely unthinkable that I'm a bit off-topic, but I'll give it a try anyway. I'm in the middle of creating a home gym in the basement of the house, my very understanding partner is letting me build and mount a modified "brå-sterk," an exercise device for skiing whose construction can be shown with these two images

The wall I have to use for attaching the "wooden pieces"/beams shown in image 2 is made up of two plasterboards, a total depth of 2 cm. As can be seen in image 1, these will be subjected to considerable force, the vertical is largely offset by the beams standing on the ground, but the horizontal, which is mainly constituted by the training individual pulling on the ropes, is not insignificant.
Just securing the beams with screws and plugs, as I've understood it, is not entirely reliable in a plasterboard. My first thought was then to secure a plywood board to the wall first to reinforce the whole/distribute the force, 2 cm plasterboard + 7 mm plywood could be attached with ordinary expanding screws. But when I attach the beam to the reinforced wall, I'm back to the screw + plug stage—and the wall isn't that much stronger.... My second thought is to mill holes in the beam so that it's only 5-7 mm thick and then run an expanding screw through it directly into the plasterboard, which then "unfolds" behind it.
As you can see, my knowledge is limited, suggestions are welcome for better ways to secure it, other materials? Are there expanding screws that are 2 cm + 7 mm + 4.5 cm (the beam) long and not extremely thick so that there's no wall left? Not tearing down any walls or investing in overly expensive things, the budget is limited...
Grateful for all suggestions :blushing:
