The Treadclimber TC1000 is the most economical treadclimber made. It provides the same workout as the more expensive Bowflex Treadclimber machines without the electronic displays and other features. The TC1000 unit is compact and mobile enough for one person to move it in and out of a home, fully assembled. The Bowflex Treadclimber is an all-in-one machine and can be used as an elliptical, treadmill, or stair stepper. The machine can turn from an elliptical to a treadclimber in seconds by simply locking a lever.
