Lengthen the lifespan of your exercise equipment with a few well-chosen exercise machine attachments, like an extra power adapter, batteries for your display and even a treadmill maintenance kit that'll allow you to easily remove dirt and ensure smooth belt performance. If you need a distraction while working out, add an exercise reading rack to your treadmill or recumbent exercise bike. Exercise reading racks allow you to mount a book, magazine or even that report for work right in front of you, so you can read hands-free. Many exercise reading racks can also hold a tablet or MP3 player, which put your library or workout playlists at your fingertips.
