Ironman M6 Treadmill Review

Ironman M6 Treadmill

Ironman M6 Treadmill

Update: This treadmill has been discontinued.

To look for an alternative, you might want to check out our best treadmill page.

The Ironman M6 treadmill is Ironman’s high end mid-priced model.

This is the most expensive unit in the Ironman series. It has the best specs and features compared to other Ironman units.

Is This Treadmill Right for You?

If power is what you want, then this machine might be the one for you. And, not only is it big and powerful, it is also priced below $2,000 which makes it more affordable compared to other mid-priced brands.

Features and Benefits

This unit boasts a 3.0HP continuous duty motor. This is the biggest and most powerful motor from Ironman. It can reach a max speed of 10mph and has a max incline of 12%. With numbers like these, you’ll surely get an intense even if you’re a hardcore runner.

The 20” x 58” running surface is also the longest deck offered by Ironman and a softer orthopedic belt was used instead ordinary belts. However, the problem with ortho belts is that it causes more wear and tear on your machine that would lead to tons of problems in the future.

The 4 preset, 8 custom, and 2 user programs give you more workout variety to choose from. While the EKG pulse grip, heart rate chest strap and the built-in heart rate program allow you to workout in your target heart rate zone for a more efficient workout.

And finally, like other Keys’ owned treadmills,(Keys Fitness owns the Ironman as well as other treadmill brands) you’ll get the long 10 year motor warranty. Other warranties include lifetime for frames, 2 years for parts and 1 year for labor.

The ortho belt is definitely a weakness. Add to this the fact Keys’ machines are known to have questionable quality, and you’ll get tons of repair and maintenance bills once the warranty ends.


I don’t recommend the Ironman M6 treadmill. Ortho belt should be avoided as much as possible especially if it is on treadmills with below average quality.

If you really want an Ironman treadmill, stick with the Ironman M5, or better yet skip the Ironman brand and save yourself a few hundred bucks by buying a Smooth 7.1HR.
