True 550 ZTX HRC Treadmill Review

True 550 ZTX HRC Treadmill

The True 550 ZTX HRC treadmill comes with heart rate features that the True 550 ZTX P doesn’t have.

And like other True models, this one also offers the best belt and deck combination in the market to give you the smoothest and most silent treadmill experience.

Is This Your Best Buy Treadmill?

If you want a heart rate controlled treadmill with huge running surface, long warranties, and excellent cushioning, then this is the model for you. It belongs in True’s top of the line home treadmill series, so expect nothing less than the finest specs and features from it.

However, with a price tag above $4,500, I don’t think a lot of people can afford it. If you don’t have enough money to buy this unit, I highly suggest you visit our best buy treadmills page and choose a quality machine that is within your budget.

What You’ll Get

This model boasts heart rate controlled (HRC) workouts. It has 5 custom time-based, 4 custom distance-based and 5 custom interval-based heart rate files to give you lots of flexibility in your HRC run. Other heart rate features include a Cruise Control program which allows you to jump from any preset or manual workouts into an HRC workout, and 6 Express Command Keys for simple access to any custom workout programs.

The True 550 ZTX HRC treadmill comes with a 3.0HP continuous duty motor that serves up speeds of up to 12mph (this max speed is higher than what models from other True home series is offering) and inclines that reaches 15%. So it doesn’t matter whether you’re a beginner or advance runner, this machine can provide you the intensity you need.

The 22” x 60” running surface is the biggest currently being offered by True. It gives you lots of room to move and be comfortable during your workout. Plus, with its magnificent belt and deck combination, this unit could very well provide you the best treadmill experience you’ll ever have.

This machine also features 4 pre-programmed workouts (Weight Loss, Speed Interval, C/V Workout, Hill Interval) with 9 intensity levels each and 3 customizable programs to give you more variety and flexibility in your exercises.

The 10 x 28 LED tri-color dot matrix display is bigger than your average True console(7 x 20). It shows you your heart rate, speed, distance, grade, time, pace, calories and Mets so you’ll always know whether or not you are progressing.

The manual S.O.F.T. select is still available in this model. With it, you can customize the softness of your treadmill to fit you more through 12 manually adjustable settings.

And finally, the True 550 ZTX HRC treadmill comes with excellent warranty. Its drive motor and all of its parts are covered for 10 years… making this one of the best warranties in its price range. Other warranties include a lifetime for frames and 1 year for labor.


Other than the expensive price tag, there had also been some complaints regarding True’s heart rate features. First of all, the console shows limited information during an HRC workout. And secondly, while you’re doing a heart rate workout, only the treadmill is allowed to adjust your intensity. If you try to adjust it manually, the machine will shut down and halt your exercise.


I don’t recommend the True 550 ZTX HRC treadmill. Its price tag is way too expensive for what it offers. If you really want a premium treadmill that provides great value, a good machine to buy is the Landice L7 Pro Sports. It is currently one of the best buy treadmills in the premium price range.
