Proform 520e vs. 720e -Detailing the Differences

Written By: Jeremy N

Runners tend to be a dedicated bunch, especially since expertise is lost when running isn’t a daily or semi-daily occurrence.

But what if the weather is bad, it’s dark outside, or there simply are no places to run? 

Then, it’s time to invest in an elliptical.

It can be hard to choose one of these machines, especially since there are so many on the market.

One of the best manufacturers, Proform, has made a ton of models that are great for the casual and dedicated athlete alike, and two of their best are the 520e and 720e.

But which is better?

What to Look For in an Elliptical:

There are a few different factors that can determine whether an elliptical is the best fit for someone’s exercise habits. 

In general, these can be summarized as construction, technology, and accessibility.

Construction refers to how sturdy a machine is.

Lighter machines and those with wheels tend to be unable to withstand a heavier workout since they are likely to move and even break.

Someone who knows they want to perform an intense running workout should avoid smaller, lighter elliptical as they will be unable to withstand the pressure and force of activity.

No one wants to exercise in a machine that is constantly moving around and a potential danger to one’s health.

Technology is how advanced the machine’s display is.

Some runners might want an elliptical that measures all sorts of factors involved in a workout, such as calories burned and heart rate.

Others might be more interested in pre-existing exercise routines and Bluetooth connectivity.

A machine with more tech will naturally cost more but might make running on the elliptical more exciting, interesting, or bearable for individuals who are bored easily.

Finally, there’s accessibility.

No one wants to run on a machine that is difficult or unpleasant to use.

If the display doesn’t make sense, if the height of the steps is uncomfortable, or if the machine is hard to adjust, then the value of the elliptical will decrease and runners will be less likely to incorporate the device in their exercise routine.

Both the Proform 520e and the Proform 720e have been judged by these three factors in the comparison to follow, as well as by their general value to a runner.

For either option, just make sure you pick up a mat to protect your flooring. The treadmill sized ones give you extra space

Proform 520e vs. 720e - Comparison

So, which one should I pick? 

This chart provides a quick breakdown of how the two ellipticals compare to one another over features that are popular and important to runners of all experience levels.

Table could not be displayed.


Ultimately, what is better is going to come down to what a runner wants, needs, and is willing to spend.

While the Proform 720e includes more features, has a longer warranty, and will last longer, it will also require a significant investment. 

In this case, it’s recommended that runners invest in the 520e unless they want some of the extra features included in the 720e like the Google Maps running mode.


Well, just from a brief comparison, the 720e honestly doesn’t have too many new or intriguing features that will be beneficial to runners seeking a workout.

So, why spend more money when the less expensive model is almost exactly the same?

If you are looking for something a little more robust, the Max Trainer might be your best bet.
