This is how the fixing for my boxing sack looks. I've been known to hang from this. It's in the basement with a lot of space around. The only drawback is that it's not really high. The ceiling is some sort of superstrong concrete that took ages and a very good drill to drill holes. Above is our tiled kitchen, so through-bolts weren't an option. I think my Master used four 8mm wall plugs and matching screws.
It holds the two of us, i.e. roughly 140 kg.
Nah, actually we tested it again when I was pregnant, so it was closer to 150.
