Hey all, I rented a hammer drill and followed the instructions per the rogue video on youtube for a r3 shorty rack http://ift.tt/1oGrhoh https://youtu.be/yH3QtVrLTEY but I drilled through the concrete slab in my basement. Is this an issue? It felt like it was empty space below and I didn't pull up any soil. So now I am concerned about having all that weight (the rack itself and the weights as well as my weight, on concrete that doesn't seem to have support beneath it. What do you think? Thanks for any tips! via /r/DIY http://ift.tt/2mXjZQX
