Hi! I've been doing BR workouts for a couple years now. I made a sandbag out of some totes and just filled with weights. I don't have the challenger bars, so to elevate I use my couch or a chair. My husband works with steel, so he made me a heavy bar to work with, but a lot of moves can also be done with single weights. I just recently got a balance trainer (on Amazon; not the bosu, but a cheaper version) Lots of moves can be modified :) Hope that helps some!
