The BowFlex TreadClimber TC5000 is the mid-range model in the company's line of stair stepper/treadmill hybrids, and it offers a number of upgraded features, including wireless heart rate monitoring; unfortunately, these features don't come cheap. More importantly, though, BowFlex has failed to correct a major problem with the other TreadClimber units, namely the fact that the resistance control dial requires you to interrupt your workout to either increase or decrease resistance.

Like the other TreadClimbers, the TC5000 combines the movements of a treadmill with a stair stepper or climber. The unit's two platforms move up and down independently like a traditional star stepper while they simultaneously operate like two mini treadmills. The resistance range is manually adjustable from 0 to 12 and the speed ranges from 0.7 to 4 mph; obviously, this isn't fast enough to jog or run on the TreadClimber, but that's the point of the machine -- instead of interval training on two different devices, the TC5000 combines their movements for a more productive workout. With the resistance and speeds set at the higher levels, even the most athletic users will find that this machine delivers a challenging but low-impact workout.

The LCD console of the TC5000 offers a wealth of electronic display information; in addition to speed, distance, time, calories per minute, total calories and total steps, this unit offers a climb indicator that visually tracks your elevation gain and a heart rate monitor that obtains information through a wireless chest strap. The computer console will remember your last weight and resistance settings, and one press of the Quick Start button will have you working out in no time without having to reenter the same information.

The TC5000 requires a little more time to master than a standard stair stepper, but it's an effective piece of equipment; the footboards alongside the belts and the supporting handlebars make it safe, as well. Unfortunately, the BowFlex TreadClimber TC5000 is not cheap, and the inability to change resistance settings while using this machine can be frustrating.


Pros: Effective low-impact workouts, solid construction, improvement over entry-level model
Cons: Expensive, awkward resistance adjustments, potential for mechanical problems
