The iFit integration brings professional coaching and scenic routes right to your home, making it a compelling option for those who value guided workouts and progression.
It’s especially well-suited for runners and fitness enthusiasts who need a reliable machine for regular use but don’t require the high-end commercial features of NordicTrack’s commercial series.
Performance and Training Experience
Equipped with a 3.0 CHP DurX motor, the S25i delivers smooth performance and rapid responsiveness. Speed transitions are fluid, and incline adjustments are handled seamlessly through iFit’s automatic trainer control or manual inputs.
The 60-inch belt length gives runners the space they need to hit full stride without feeling restricted. FlexSelect cushioning lets users toggle between a softer impact or a firmer, road-like surface, adding versatility to your workouts based on recovery or training goals.
The treadmill supports high-speed running (up to 22 km/h or about 13.7 MPH), making it a capable machine for sprint intervals, tempo runs, or steady-state cardio sessions.
Smart Features and User Interface
The Nordic S25i features a 7-inch high-contrast display that presents key metrics such as speed, time, distance, incline, calories, and heart rate. While it’s not a full-color touchscreen like on higher-end models, it is clear, functional, and user-friendly.
Through iFit (subscription required), users gain access to:
- Thousands of on-demand, trainer-led workouts

- Automatic speed and incline adjustments
- Goal-based training plans and daily suggestions
The built-in speakers, fan, and device holder round out the entertainment and comfort offerings, ensuring a more enjoyable workout environment.
Durability and Build Quality
The Nordic S25i is built on a solid frame with reliable components that support consistent use. Its 3.0 CHP motor is strong enough for most users, and its 298 lb (135 kg) weight capacity provides peace of mind for larger individuals.
FlexSelect cushioning and a durable deck ensure longevity while reducing wear and tear on your joints. Overall, the treadmill holds up well for those engaging in regular to intensive cardio training.
Storage and Portability
Despite its sturdy build, the S25i is space-conscious thanks to its folding mechanism. With the SpaceSaver design and EasyLift Assist, the deck lifts vertically with minimal effort, allowing you to free up floor space when not in use.
Built-in transport wheels make it relatively easy to relocate the treadmill around your home, though its size and weight may require assistance during initial setup.

The NordicTrack S25i strikes an excellent balance between performance, smart features, and usability. With a longer belt, stronger motor, and incline capabilities, it’s a step above most entry-level treadmills. iFit integration transforms the treadmill from a static cardio machine into a dynamic training platform, offering personalized workouts and professional coaching.
While it lacks a color touchscreen and relies heavily on iFit for full functionality, it still delivers tremendous value for intermediate users who want a robust and engaging workout experience at home. If you’re looking for a reliable treadmill that keeps you motivated with advanced features and flexible programming, the Nordic S25i is a strong contender.
