What are calibrated discs in the gym?
Question by Guest | 17/09/2019 at 19:26
Recently, I talked to a colleague about my new gym. One of his first questions was whether there are calibrated discs in my studio.
I have no idea what that could be. To ask him was also out of the question for me, otherwise he will think that I'm stupid. So can anyone tell me what calibrated discs are?
