You might want to do a search as this is a common question ... one discussion link actually has photos of people's workout space. Temporarily, I'd put down puzzle mats (that's what I have done). My dream, if I were to build a house, would be to put one of the floors from GreatMats.com down. Go to their website, they have some newer materials now than when I purchased my puzzle mats. Good Luck! Deb
