Question: I am on the top floor of a loft apartment that used to be a factory. I want to install several hooks or some other fixture into my concrete ceiling from which I can hang gymnastic rings, a punching bag and a swing/hammock. I am about 200lbs and if I were to use a safety factor of 5, each hook would possibly need to be able to support 1000lbs. Given that there is inevitably a higher impulse everytime I get on/off the rings or punch the bag, would the 1000lbs be sufficient? Which then leads to - how and where can I get hooks or some other type of fixture that would be able to take this load and how can I get them into my concrete ceiling? 

I do not have experience with home improvement so I would appreciate as much details as possible.

Answer: 
I would be very reluctant to bolt directly into a concrete ceiling for what you're doing for two reasons:

1. Concrete fails explosively. Unlike wood, which will splinter first, or metals which will sag or bend a little, concrete will just pop.
2. Concrete is weak at handling tensile forces; it's best at compression. (even sheer breaks in concrete tend to be at a 45° angle, and calculated as tensile breaks, not sheer.

If you *really* wanted to do this, the most important thing would be to use the longest bolts that you could, as when the concrete fails, it's going to rip a cone of concrete out (assuming the bolt doesn't just come loose, and if it's longer, you might feel it slip first and get some warning). The longer the anchor, the larger cone it's going to have to rip out, meaning the more surface area that's going to be required to break.

I'm not professional engineer, but I still have some of my college text books at home, and might have some of the formulas to calcuate the strength, but you'd also need to know the characteristics of that specific concrete mix.
I hung a heavyweight workout bag with the anchor recommended here in a concrete ceiling. Used some epoxy as well to set anchor. Attached eyebolt with a coupling sleeve to anchor bolt. Marked bolt and nuts to monitor any movement or working lose. 1/2" bolt sneered after about 16 months of uses between the jam nut and coupling. Will try the angle iron with two anchors to better absorb shock during use.
