The ProForm CR610 is an treadmill model that is no longer manufactured as of 2013, though you may still find used models for sale. It has several advanced features and folds up to save space when you are not using it. Make sure the unit is in good working condition before taking it home and setting it up.
The CR610 can handle loads up to 250 pounds. Do not use this machine if you weigh more than this. The maximum speed is 10 mph and the incline adjusts in half-percent increments. You have the option of controlling the speed and incline manually or choosing one of 6 included personal trainer programs that automatically adjust the speed and incline for you. Use the buttons on the console to change the speed and incline of the walking belt manually.
