Row of mirrors from Home Depot used in a home or garage gym. Very affordable when done this way; much cheaper than professionally installed mirrors from the local glass company. Great way to replace those $10 mirrors you have lined up on your wall.
Mirror, On The Wall - It's got nothing to do with vanity. Hanging a mirror on the wall of your home gym will allow you to check your form as you lift weights, so you can keep a proper posture. A mirror also can brighten up a small space, and, of course, help you track your progress.
