Help With Mounting Gym Rings Please

So I've done a bit of research on how to mount rings and have found some options. The main one being like this, where you screw a 2x4 or something into the ceiling and then hang hooks from there, like this:

But I would prefer to use something like this to attach directly to the ceiling:

Thing is I'm not sure if it's safe. Would two of those bolted into two separate joists be strong enough to hold a person (about 160 lbs)? Maybe it depends on what type of joists I have in my building?

Or is it better to attach a 2x4 to the ceiling and use that as to better distribute the weight on the ceiling?

I don't have a lot of space options as I'm in a condo. No basement with uncovered joists or anything like that.

I'd like the installation to be as inconspicuous as possible, which is why I'd prefer the second option.

Would really appreciate any feedback or pics of people's set ups.

Thanks!

No, not safe.

See the Facebook group "Safety in Aerial arts" for a lot of information on rigging different types of equipment. While GB isn't performance, or circus, or theatrical rigging, most of the movements are dynamic: this increases the load far beyond what you actually weigh.

Anything you try to rig from should have a safety rating. 99.9% of items from Amazon won't have any rating (it's usually stamped on them) or any indication of the safety factor (the maximum load before failure divided by the "safe working load".)

Try this: get some bathroom scales and weigh yourself. Now slowly step onto the scales and watch the needle. No matter how slow you go, you will always make the needle go over  your "static" weight. Thus, even if these attachment points could handle your weight, you will make dynamic movements and increase the load on the rigging points when you: a) do a hinge row, b) invert into a skin the cat c) do a ring dip. And so on.

Specifically to the picture:

• The eyebolts are not forged as a ring - you can see the gap in the circular part.
• There is no picture showing how the bolts are mounted onto the "2x4" wood. If they screw in, they are not safe, especially into softwood.
• There is no picture showing how the "2x4"s are mounted onto the ceiling joists.

The safest option is to get a cheap power rack with a pullup bar and rig from that. Most power racks are more than strong enough for bodyweight exercises. you can also use dowels in the power rack holes to make a reasonable-enough set of stall bars.

 

Hey thanks very much for the detailed reply!

So both options are a bad bet?

Power rack is a good idea for sure, but I don't have much space left in my place to fit one. Maybe I can move things around a bit.

Edit: I suppose a wall mounted chin up bar is also a bad idea due to excess stress from moving around etc...

The amazon fitting is underrated: 1000lbs is 454kg. If the rating is true (and this has been tested), then that is 4500 kilonewtons. Rigging for aerial acts usually mandates 22kn and above. Note that this is for doing "drops" on silks, aerial straps or other apparatus: your full bodyweight dropping a metre or two or three. Maybe you won't be doing clapping ring handstand pushups on rings I'm sure not, but I like to work with something that can handle at least 10 times my bodyweight: 70kg/154lb x 10 is 700 Newtons, so times 10 for a 10x safety factor gives 7kN, and 10kN is the next rating up for any equipment rating that I use so I'll use that.

Rigging fittings bought from Amazon, unless it's a "proper" seller's store (Petzl, Rock Exotica, and known climbing or rigging brands), often don't have any provenance (traceability). Multiple sellers' products are commingled in Amazon's warehouses, so even if someone is selling "legit" gear it might be mixed in with cheap knockoffs. Yes, I'm paranoid, I've read about it often enough. I've written a few things here about safety - it only takes a slight mishap and you lose six months of training. I've spent 7 years in rehab and am only now getting back to where I was before. So I worry - really, I do - about how people rig things at home.

It is possible to get wall-mounted power racks, but you're living in an apartment. Not sure if you'll be able to get the hammer drill out... Have a look at https://old.reddit.com/r/homegym/ for some ideas about different types of racks. There are mostly US home gyms, so the brands will make sense.

Wall-mounted chinup bars are ok if they are mounted correctly - though I'd probably get a tradesperson to do it (or at least go to a good hardware shop and ask someone). It'll depend on the type of walls you have. Proper concrete is best, as you can drill and then chemically cement the fixings in. Wooden studs (the uprights in the walls)...you really need to drill all the way through, especially for the top mounting point (it will be under the most "pull-out" force/tension). So screw-in fixings (coach screws) might not be strong enough.

I probably would be ok with coach screws for mounting stall bars, as they are a lot closer to the wall and the leverage on the fixings isn't as high, plus the bottom of most stall bars is also on the floor which give it some support.

Thanks very much again!

Ya so I'm definitely not gonna get something off amazon. I found a Canadian brand which looks like good quality and have the following options:

https://www.roguecanada.ca/rogue-jammer-pull-up-bar

https://www.roguecanada.ca/p-6v-garage-pullup-system

Second one would probably be my first choice as it's the smallest, but not sure it would be safe to use rings off of (although I did read one comment review where someone said they were using it for rings).

The first one would be great, but don't think I have the space for it.

And I'll check out the old reddit post thanks!

Edit: this thing is also an option, but I haven't found much on it in terms of reviews:
