Bowflex TreadClimber TC20

This machine provides the user with three different types of exercise equipment rolled into one. The Bowflex TreadClimber TC20 is able to perform the function of a treadmill, a stair climber and an elliptical trainer.

This ability to combine three different types of exercise machine into one unit has resulted in the "treadclimber" being one of the most popular cardio exercise devices on the market.

This is the top level machine out of the three models in the range and is electrically powered. Twelve intensity settings allow the workout to be customized to meet your comfort requirements and your experience level whether you are a beginner or expert.

Here are the main features:

… treadmill workout

The running surface is split down the middle so that in actual fact there are two independently powered surfaces. When the machine is put into "treadmill" mode, however, the two running surfaces come together enabling the two running surfaces to operate in unison and give the appearance and feel that you are running on one uniform, rolling surface. In this configuration the device behaves exactly as a conventional treadmill.

… stairclimber workout

When the the machine is put into it's "stairclimber" mode the two surfaces that were joined together to form the treadmill running surface now act independently and form two separate "treadles". The device may now be used as a conventional "stairclimber" offering a good cardio workout, but with the added benefits of low impact on the joints that this type of exercise affords.

... elliptical workout

Putting the machine into it's "elliptical" mode combines the actions of the TC20 when in it's "treadmill" and "stairclimber" mode and produces an action which is similar to the action of an elliptical exercise machine. To achieve this the "treadles" move independently as is the case with the "stairclimber" mode but additionally the surface of each "treadle" moves like the surface on a treadmill. This again results in a good cardio vascular, but low impact workout.

... vary your intensity

The treadclimber allows you to select from a range of twelve different intensity settings to enable you to adjust the amount of resistance you wish to apply to your workout. You can adjust your workout based upon your level of expertise or your comfort level.

... track your progress

A fully back lit LCD display provides useful information about your workout progress. On this display you are able to track your  Speed, Distance, Time, Calories and Heart Rate during your workout.

… take the shock out of exercising

Walking and running are the most natural and enjoyable forms of exercising you can engage in but the continual pounding can take a toll on your joints.

With the device in either it's "stairclimber" or "elliptical" mode the harmful impact on your ankles, knees, hips and back is greatly reduced compared to running on a treadmill.

... elliptical without restraints

Although conventional elliptical machines are able to provide an excellent cardio vascular workout with minimal impact on your joints they do have one drawback. This is because on a regular elliptical machine your feet are locked onto the foot pad and can become numb after some time. This is not the case with the elliptical mechanism on this machine where your foot is able to move naturally and so avoids this problem.

... GO Coach

The G.O. Coach workout is a programmable (goal oriented) workout. The goal is to climb the three landmark structures (a mountain, a tower, and a building) weekly.

As you work out, your progress on the current landmark structure is displayed with landmark segments. The Console records your G.O. Coach Workout values, so you can stop a workout and continue it at a later time.

The G.O. Coach weekly Progress Display provides a quick visual summary of where you are on your weekly goal. As you workout, segments on the progress display are shown. When all of the segments are shown, you have completed your weekly goal. 

You are able to create two personal, user profiles to record and display your progress toward your weekly goals and the console will track all your G.O. Coach Workouts for the week.

... safety key

The equipment comes with a safety key and lanyard. In order for the device to be operational the key must be present in the control console. This means that with the key withdrawn the treadmill cannot be operated by unauthorized users such as small children.

The safety key has a lanyard with a small plastic clip attached to one end which can be clipped onto the users clothing. If the user were to accidentally trip or fall the key is pulled away from the console causing the machine to come to a stop.

Ellipticals make my knees hurt , and i don't have knee problems.
The Bowflex doesn't bother my knees at all.

Easy to walk on for a slug like me but i also get a great workout in a short amount of time.

Only have had it for 3 weeks and my cloths are fitting better and lost 3 pounds without changing a thing.

Maybe i should watch what i eat and there would be a big difference.

This was a gift for my wife that I purchased for her. she hasn't been home yet to use it.

I have been using it for a week now and I am already seeing a difference.

I started out with less time (20minutes) and changed to 30 minutes without any problem after my third workout.

I wish there was more than two profiles on it as we have three people using it but other than that I love it!

I use this every other day to get into shape. I went from 100% couch potato to moderately active in less than a month.

When I first started it was hard to do more than 30 minutes at 1.0 mph, but now I can go for an hour at 2.2 mph.

The machine is easy to use and adjusts to you as you become more athletic.

It is low impact and has great safety features.

I have had some problems with the unit turning itself off mid workout and loosing my data (mileage, calories burned, etc.) I am not sure what causes this.

The display has also already lost some of it's lighting, but I can still read the screen well enough to know my progress.

Just beginning workouts at 66 yrs old and finding the treadclimber to be much easier on joints than my treadmill.

I had to start at a very slow pace, but I am advancing slowly. This is the greatest workout I have experienced in the shortest time.

I love this machine and would definitely recommend to everyone.
