Smith Machines offer a great deal of safety and variety when performing certain exercises. Smith machines have an attached Olympic bar which allows the user to perform squats, benching and other exercises in complete safety and without the worry of getting "stuck" during an exercise. It's a great piece of fitness equipment to add to your home gym especially if you find yourself weightlifting on your own. Many of our smith machines can be purchased with attachments such as lat pulldowns, pec decs and leg developers. Smith machines usually use either linear bushings or linear bearings to create the smooth movement of the Olympic bar. Linear bearings are superior to the bushings but cost quite a bit more.
