I decided to install a ceiling TRX mounting bracket in the basement
Based on the good reviews on Amazon decided to got with Faswin Wall Mount Bracket for Suspension Straps
Installation
My basement is unfinished and has an exposed ceiling. This is an old house and has solid hardwood joists. I debated whether to mount to a single joist but ended by deciding to attach it to a load bearing sistered joists. I settled on the latter surmising that i could distribute the wall mount's load across 2 joists rather than just one.
I centered the wall mount holes on both joists (pic above) and marked the holes. I then used a drill bit to drill pilot holes. At this point I should mention I did spend a good amount of time researching the right size pilot hole. Here are two of the many searches and pages I went through to cross-check and ensure I had the correct drill bit -

Once the holes were drilled, I installed the bracket using the provided lag screws.
NOTE - I hand fastened the lag screws using a ratcheting socket wrench rather than using an impact driver. Even with the pilot hole, this was tough as it required careful application of good amount of force to drive the lag bolt through the hardwood joist. I again surmised (after a lot of research) that a manual fastening provided a lower risk of splitting the wood as the bolt needed to be exactly perpendicular.
Note the overhanging mount (pic above). I chose to install the mount this way - because the holes would be centered with the joists. Also, one of the joist was uneven (red arrows) and there was a ceiling light (red arrow). In my opinion, the mount is very well welded, that the extra lip overhanging does not take way from the structural stability of the mount.
