@talentryto- I don't think that you have to buy expensive flooring to get the type that is perfect for doing aerobic exercises. I like to do exercises at home, and have found that the right kind of rug is convenient, inexpensive, and ideal for all types of aerobic exercises. They are also very movable, so you can take them where ever you want to work out.
Not all rugs are good for exercising on because a lot of them slip easily or are too thin to absorb shock. That is why you have to look for specific features when you shop for a rug to do your aerobic exercises on. Plushy rugs with dense fibers are ideal, but you also have to check the material that is on the backsides. Rubber is perfect for keeping small rugs in place. You can also look for terms like no-slip or fall-proof on the tags when rug shopping.
You also don't have to spend a lot of money on your aerobic rug. Retail and discount stores carry a wide selection of rugs, and often run sales on them as well.
