My wife and I do a lot of high impact cardio. Are these tiles suitable?

Our 1/2" Tight-Lock Tiles are a good floor for high-impact workouts. They will give plenty of shock absorption for any type of exercise. If your joints are a little more sensitive, we do have a wide range of high-impact flooring that is more suitable. You can find these rubber tiles, rolls, and mats on our High Impact Flooring page.
