The XTERRA Fitness TRX3500 Folding Treadmill is a good option for shoppers with smaller treadmill budgets. It meets performance standards set for higher-priced treadmills. I also like that the TRX3500 supports two user profiles and delivers various customizable exercise programs.
Key features include a two-ply 60″ x 20″ workout surface, a 3.0 HP drive motor, a power incline to 12 percent, 30 preset workout programs, and a heart rate-controlled workout program with a wireless chest strap. Unfortunately, the HR chest strap does not come included with the machine.
Workout data is shown on a 6.5″ LCD with blue backlighting for easy reading. An animated racetrack graphic illustrates your progress, and the window displays multiple data points. Many other low-priced treadmills have smaller readouts and require scanning to show different data fields.
You can pair an Apple or Android mobile device via Bluetooth with the XTERRA Fitness TRX3500 Folding treadmill to export your calorie burn, distance covered, heart rate, and other exercise statistics. The free XTERRA Fitness app is also compatible with Fitbit wearables and other fitness mobile apps.
