The XTERRA 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 how the TRX3500 supports two user-profiles and delivers a variety of customizable exercise programs.
Key features include a two-ply 60” x 20” workout surface; a 3.0 HP drive motor; power incline to 12 percent; 30 preset workout programs; and a heart rate controlled workout program that works with a wireless chest strap (not included). Additionally, the console can store two user-profiles and lets each user store two custom-designed treadmill workouts.
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 at once. For comparison, 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 TRX3500 Treadmill, and the fitness machine will automatically export your calorie burn, distance covered, heart rate, and other treadmill exercise statistics. The free XTERRA Fitness app is also compatible with Fitbit wearables and other fitness mobile apps.
