Fantastic Exercise Mats
These are perfect for all exercise. I use them in my basement and do plenty of P90X, Insanity, etc. exercise routines on them. They provide impact resistance and good grip for jumping and moving around. They are heavy enough to not move around when jumping and landing. They are more expensive than the other tiles, but are well worth the price and I know that they will last years for me, especially given that they are for personal use. They were very easy to install. I got the beveled edges and they look great, very professional.
