After many hours of research....I purchased an energy block floor from Gerstung. I have to say I wish I had done it many years sooner. I am a home exerciser and I love Cathe's workouts but, my knees, ankles, hips took a beating after many years of jumping around on mats in my basement. (Good mats too) A little pricey but, worth every penny. I purchased a 12' x 12', very simple to put together (10 minutes) and all I can say is what a difference!!! Just a little information for those looking at gym floors.
Good luck
