I was reading the injured thread on the ask cathe forum and it was talking about working out on a cement floor can make you more prone to injury. Well I'm wondering what you all think of my workout surface. The house I own has no basement, therefore, the first floor is the foundation and under the nice looking flooring is concrete. I workout in my living room, and we put down really really plush padding so the floor feels really soft and a good quality really plush rug on top of that. When you walk in there it feels nice and cushy to the feet. When I do my workouts in there, am I prone to injury as if I am working out directly on concrete or becuae of the good padding and good rug am I protected from the concrete danger?
