When I drilled the first hole for the second side however, the wall appeared to be brick. Its cement for sure, just what you would call a cinder block I assume.
There's 28mm of material, goes hollow, and on the 100mm point there's material again. The wall from the side is 22\~cm wide, so I assume Its 28mm --- 28mm --- 28mm. I marked it for you to understand in the picture. The X is for the end of resin wall plug, well get to that in a moment.
So here where I need help at. I am 90kg, Each pullup bar fixing is about 8kg, the bar itself another 6kg\~.
Like I said, one side is fixed to solid concrete.
What type of anchor should I go for? The best "cheap" ones I found are a molly kind that the seller from aliexpress say they can withstand "Maximum load capacity: 1100kg; safe load capacity: less than or equal to 400kg". Speaking about an M8-80MM long.
1. Do you think it can really withstand the weight? Remember there are 2 anchors on the fixing (one side). If you divide my weight by two, add in the bar, fixing, and pull load...I will assume we are speaking about 100kg max? 2. Can the cinder block even withstand the weight, without regard to what anchor I use?

Now there's another option of buying special resin wall plugs and a the resin itself, rods, which will cost me alot more.... but if those two molly anchors can really hold it, then, you know....
