The Bowflex TreadClimber is a treadmill/stair climber hybrid that features a smooth-moving track and variable speeds to fit every fitness level, notes Bowflex. As of 2015, Bowflex offered two TreadClimber models that feature motor speeds up to 4 or 4.5 miles per hour, 2- or 3-year warranties and the company's G.O. Coach technology for extra motivation.
The TreadClimber's up and down motions stem from the user's momentum, which ensures the machine keeps pace with the user's stride and fitness level, notes Bowflex. The TreadClimber uses a quiet motor that allows the user to still participate in conversations in the room or listen to music or watch television while exercising.
