This elliptical has thousands of workout programs to choose from with its included iFit subscription. iFit trainers lead you through fully immersive and interactive workouts for convenient and effective sessions. It has a maximum weight capacity of 300 pounds, providing a sturdy frame for heavier set people to feel comfortable on. Plus, it has 18 different resistance levels, 0 – 20 degree incline adjustability, and even adjustable stride length — all for under $1500. These features at this price point make the Proform Endurance 520 E one of the best mid-range ellipticals on the market.

Consider Proform Endurance 520 E if...

  • You need an adjustable stride length. If multiple different household members of various sizes use the Proform 520 E, the adjustable stride length on this elliptical makes sure that everyone can workout pain and worry-free. You can easily adjust how long you'd like your stride length to be to best suit your height and desired workout intensity.
  • You want adjustable pedals. This elliptical's cushioned, oversized pedals are adjustable, allowing for many different foot positions. You can adjust to where you're most comfortable to avoid any aches or pains.
  • You like listening to music via speakers. The Proform Endurance 520 E's auxiliary audio port and built in speakers let you plug in your device and select music through the smart touchscreen for a convenient listening experience.

Avoid Proform Endurance 520 E if...

  • You don't use incline settings. Many ellipticals don't feature an incline system, which makes the Proform Endurance 520 E different. If you prefer a traditional elliptical experience and don't like training on an incline, consider the Sole E95S instead.
  • You don't want a smart display. While many love using a smart display when working out, you may find it distracting or even discouraging. If you'd rather stay focused on your movements and not your metrics, opt for the Proform 6.0 ZE, which has a much smaller and simpler screen.
  • You want a built-in fan. Unfortunately, this model doesn't include a built-in fan to keep you cool while working out. If you want this feature, consider the Nordictrack Elite 10.9.
