Hi Carla,
Funny you should ask.
My DH recently came back from deployment for a few weeks. He noticed the picture of the road trip on Cathe's home page. He looked over at me and said, "What is this about a road trip?" I proceeded to give him the 411. I must admit that I was confused at why he asked. He then said, "Why didn't Cathe annouce this!" (like he knows Cathe) Again, I was confused. I replied, she did. It just wasn't the right time for me. He then left the house and returned with 12 eight packs of puzzle mats from Sam's club for my workout room. He actually felt bad that I didn't attend the road trip.
I now have a wall to wall foam floor. I already had 28 Prospirit mats. So, my floor is dual layer foam matting to include 30 square feet of closet. There is an 11 x 8 foot cardio deck, which is covered in black Prosirit mats for my stationary cardio equipment and heavy weight bench. The exercise area is an 11 x 10 blue mat with a few green agility grid squares. I was a little nervous about this at first but I love it.
The Prospirit mats were a bit slippery but the Sam's club mats are not. They are firm enough to provide lateral support and give just enough to absorbed impact. Sam's club mats were so much cheaper than the Prospirit mats. I have tried various types of cardio workouts and I am completely satisfied with this floor. They work well for stretching and other exercises where I lie down on the floor. I probably didn't need two layers, but you would probably need two layers over concrete. Did I mention that I love this floor! I looked into different flooring options but I am glad that I have this floor. It ended up being about half the cost of some other puzzle mats and 1/5 the cost of other flooring options. Cathe does has some info about flooring on her home page.
Goodluck,
jordan
