I workout at home in the basement with a standard North American floating slab concrete floor. Has anyone ever dropped a weight and cracked the floor?
I do squats and 400ish lbs deads and have never had to dump the weight and I wonder how much the floor can take. I do have a rubber mat found at all gyms as protection, but it isn't that thick compared to 400 lbs imo.
I want to start cleans/snatches in my routine but I want to be able to drop the weight if I have too. I am a little worried abut what might happen if I do have to dump it from shoulder height.
So, how hard/easy is it to break the floor?
What can be done (in addition to the mat) to protect the floor?
