sams club from time to time has sold rubber interlocking tiles about 18 x 18. One side is colors and the other is lack. Its a good flooring for home gyms. They usually sell them as playroom carpet or similar.

I go two 3' x 5' mirrors for our exercise room at HD. They're mounted side by side. The bottom of the mirrors are in a J channel, which is screwed into the studs, and the tops are held in with two mirror clips on each mirror, which are also screwed into studs. The size is great. When we mounted the mirrors, the room looked double in size. And 5' high is more than sufficient to see everything when I'm exercising. It sure helps motivate me to stay in trim.

Thanks, y'all! I think we invested right at $250 in this room's "makeover" (including the paint, one mirror, the weight bench and mat), and it is an infinitely more pleasant place to be now, so that was money well spent. I also take pride in the fact that we used much of what we already owned. That lamp? It's not ideal, but it's a nice vintage lamp and it works just fine to shed more light on my activities in the room. The "art?" I made three of the pieces, and if you look closely, they do LOOK homemade, but I don't care. I find myself looking forward to being in the space (ok, so it's only been a couple of days since we painted and revamped, and the 'new' might wear off at some point), and even enjoyed the time I spent there this morning before the crack of dawn. I've just committed to a 5K that takes place in a mere two weeks. Luckily, it's billed as a run/walk, and it's so close to my house that if it absolutely sucks, I'll just walk home and call it a day. ;-) But it feels great to have signed up for something that motivates me even more, and is for a good cause (benefits our local animal shelter). I find myself very much looking forward to the days ahead, and time spent both outside when I can find the time (and temps allow), and in this formerly under-utilized little room at the back of the house.

Thought this article might help. Consider your flooring and if there is natural daylight in room, your favourite color to help you feel relaxed or energized.
