Protecting your joints and other components of your body is an important part of any exercise routine. For those who enjoy working out at home, buying some sort of cushioning for their personal gym area may be required. In my case, most of my house is either wood flooring or stone tile. My preferred method of exercise is the use of workout videos, so I need to have a stable, firm, yet shock-absorbing surface in front of my screen. These ProSource exercise Puzzle Mat pieces are a great choice for this. They're lightweight, yet durable. They are easy to assemble, but hold together strongly. The pack that I received had six pieces in it, making a total of 24 square feet. I tend to move around a lot when I work out, so I will probably be buying another set of these mats to give me a greater area for motion. When working out on my wood floors, all the jumping and moving I do can make a bit of noise, too. Having this mat set also provides a bit of noise reduction for my home as well. If using hand weights, I always have to be careful when I put them down on my wood floor, as they could damage the surface. The ProSource mats are an easy way to protect my floor from damage also. The set also comes with 12 end borders, to provide a finished edge to the outside of your mat area. While these borders are necessary, I really like how they make the matting look, with the smooth edge. ProSource has made an excellent product with their Exercise Puzzle Mat set, and I can heartily endorse this item.
