ProForm 850 elliptical trainer feature with 18-inch stride length. It comes with 2 built-in speakers and universal dock which can charge and play MP3 player. It has 12 workout programs, handlebars grip heart rate monitor and lifetime warranty on frame.
ProForm 850 is sturdy and comfort with arms level. Resistance can be customized by digital adjustment or let it automatically adjust by Personal Trainer programs. This machine differs from others in that it has two games to play during the exercise, which is not too difficult. The controller responded by tapping lightly but I think it is too small screen size.
