Treadmill Review

There is not much of a difference between the Gold’s Gym Trainer 520 treadmill and the Gold’s Gym 420 treadmill, yet the Trainer 520 costs $20 more than the 420. All of their specifications are identical and the only clearly different aspect is the colors used on the treadmills’ consoles and the telescoping lift system on the deck of the Trainer 520.

As neither treadmill is of that great a quality, the fact that the Trainer 520 is a bit more expensive than a treadmill it is identical to is not impressive. Overall, we would not recommend the Trainer 520.  



The cost of the Trainer 520 is $549.

The Trainer 520 Is Built For Users who:

  • Are on a budget - As some people looking for a decent treadmill are on a strict budget, they may find the Trainer 520 a good option.
  • Prefer to walk - The Trainer 520 is only good for walking and can be very wobbly when users break into a jog or run.
  • Need a small treadmill - Compact and slim, the Trainer 520 is a good fit for households which are limited on space.

Why The Trainer 520 earned 2.2 stars

The Trainer 520 treadmill is an okay treadmill. However, there are some drawbacks which may be deal breakers for you.

  • Very short warranty - With only 90 days to have labor and parts taken care of and 5 years covering the Trainer 520 frame, the warranty is very short.
  • Restrictive treadmill belt - The treadmill belt measures 18” wide and only 50” long on the Trainer 520.
  • Budget quality construction - There is a budget level of build construction that the Trainer 520 exhibits which is less than ideal. More plastic than metal makes up the Trainer 520 and it wobbles alarmingly underfoot.

Treadmill Reviews has reviewed many budget treadmills, and we have found the Trainer 520 is not one of the better budget treadmills.

Trainer 520 Review: Build Quality
  • Warranties - 5-year frame & motor, 90 days for parts & labor
  • Belt - 1-ply
  • Cushioning - AirStride™ Plus
  • Customer Support - Live chat, phone, email
  • Return Policy - 30-day trial period

A 10% restocking fee comes with any returned Trainer 520 treadmills. They also need to be authorized to be sent back within the 30-day trial period. If your treadmill is damaged or defective upon receiving the Trainer 520, you can receive a full refund or exchange with no restocking fee to pay.

The warranty on the Trainer 520 is very short, much like all the Gold’s Gym treadmills. With only 90 days for any labor or parts issues to be resolved, we are very concerned for the projected longevity of the Trainer 520.

Bottom Line Review Of The Gold’s Gym Trainer 520 Treadmill

While the Trainer 520 is not the worst treadmill we have tested and research, it certainly doesn’t rank very high with us or consumers who have purchased it. Not only is it not a very sturdy treadmill, but as one verified purchaser put it “It has some good features but it is like running on cement.”

So, while there are some decent features on this budget treadmill, we would strongly recommend you look over our best treadmills between $500-$700 to see your options in this price range. If you are willing to go a bit higher, the best treadmills under $1,000 will allow you to significantly raise the quality of the treadmill you bring home.
