Ironman M4 Treadmill Review

Ironman M4 Treadmill

Ironman M4 Treadmill

The Ironman M4 treadmill is one of those Ironman models that you rarely see on sale.

But it still comes with power, features, and specs you would expect from an Ironman unit.

Is This Treadmill Right for You?

If you’re looking for a decent mid-priced treadmill, then this model is a good choice. However, I think you’ll get more value for your money by buying the Ironman M5, especially when you can get it at a discount.

Update: This treadmill has been discontinued.

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

Features and Benefits

This Ironman model offers 2.5HP continuous duty motor that has a speed range of 0-10 miles per hour and an incline range of 0-12 percent. This motor has enough power to satisfy serious runners.

The big 20” x 56” tread belt is enough to allow you to move freely and have a comfortable workout every time. And with its fold-up design, you can save valuable space when the machine is not in use.

And finally, like other Keys’ owned treadmills,(Keys Fitness owns the Ironman as well as other treadmill brands) it boasts the classic 10 year motor warranty which is one of the best in the price range it’s in. Other warranties include lifetime for frames, 2 years for parts and 1 year for labor.

Just like other Keys owned treadmills, this Ironman model also needs some quality improvements. It is made from cheap parts which is the reason why its quality is not at par with top machines in its price range.


I don't recommend the Ironman M4 Treadmill. I think this is a decent machine to own but I still believe that the M5 model is a better option if you want a mid-priced Ironman. Or better yet, skip the Ironman brand and just buy yourself a Smooth 7.1HR which is our best buy mid-priced treadmill.
