I want to have a pair of still rings for training purposes in my room. To be more specific I want a pair of adjustable and storable still rings and for that, I need two screws in my concrete ceiling. My main concern is that they can hold my body weight. I'm around 65 kg and I will NOT swing with the rings (the room's too shallow anyways). I want to do exercises like L-sits, planche, pull-up, muscle-up etc. So I'd say the screws would need to hold a maximum of 150 kg in an extreme situation.
What size and kind of screw should I take and is there anything else I should be concerned about?

There are two primary types of anchors for concrete. I'd trust either if properly installed. Holes must be drilled cleanly and to the proper size. Bolts must be of the correct diameter and length. Both require fairly large holes (7/16" to 5/8" or so).
Sleeve or Wedge Anchor (with integrated bolt)
Lag Shield (with standard lag screw)
