I asked about this is in the "small questions" thread and was told it's ok to hang weight from your ceiling, but I am still too nervous and want a second or third opinion. I bought these on Amazon:  They're for various body-weight exercises. I generally like to use them for pulling, wherein I lie down underneath them and pull myself up toward wherever they are suspended from. If I'm to do that, the best place to suspend them would be from the ceiling. However, I really, really don't want to gently caress up the floor joists (they'll be in the basement). Another, worse option is to install the anchor high on the wall. This isn't ideal, but if it's the only safe way then I'll live with it. Here is the anchor I bought:  And here are the gigantic screws that came with it:  And for good measure, a rough view of the space I'm working with (that little black thing in up in the corner is my magnetic stud finder):  So, my questions for this thread are: 1) Can I screw this anchor to a joist in the ceiling and then yank on it? I weigh ~155lbs. 2) Does it matter whether I have engineering I-beams or some other kind of joist? 3) If the ceiling is a bad idea, what's a good way to attach it to the wall? I found a stud, but these screws really are gigantic and I'm nervous even about using a wall stud (what if I just nick the side of it, what if it splits, etc.).

Unfortunately nobody's going to be able to give you a really definitive answer, and if you're really unsure the best way to confirm is to talk to a structural engineer. That said, I agree with the broad conclusion of the fix it fast thread which is that it should be fine, joists are quite strong. I would be more worried about pulling the bolts out than actually damaging the joists. You could always use two joists if you wanted, either by attaching some wood to both and then your anchor to the wood, or with two anchors. Just make sure you wind up with something more like a top rope trad anchor and not an American death triangle. I have no experience with engineered joists so I'm afraid I can't help you there.

Is there any part of your basement that is unfinished where you can take a look at the joists? Or even if you are able to look around an air vent or light fixture.... Is the top bar of your dip rack load bearing? If the base doesn't interfere with your exercises it might be easier to just sling the top bar.

That's a good idea to take off the air vent and light fixture. I'll try that. As for the dip rack: yes, that bar on the top would be perfect (that was my original idea, as that's how these things are anchored at Planet Fitness), except the whole stupid thing topples when you try! I can do pull-ups on it just fine, but it seems like any force in a direction it wasn't designed for is bad news.

But either way it sounds like you've got a (small) project on your hands.
