Make a wood platformI live in a town house and my room is on the second floor, when I do deadlifts and the bar hits the floor, obviously you can hear it and it makes an impact. I'm afraid at some point I'll crack the concrete. Is there a certain type of mat I can buy, that is designed specifically to take the impact of someone deadlifting? I was thinking I'd need to buy the kind of mat that is used in wrestling arenas outside the wrestling ring. They have mats at Dick's sporting goods, but the mats are really thin.
