What We Like:
- Program Variety: The LifeSpan TR4000i Folding Treadmill has 21 workout menu items. These are grouped into fitness goal categories including weight loss, cardio fitness (interval and constant heart rate control), sports training, and healthy living. Workout feedback is shown on a 6″ LCD, which includes Time, Calories, Distance, Heart Rate, Steps, Speed, Pace (time to complete one mile), Incline, and Elevation Gained. Exercise data can be transferred wirelessly to popular fitness apps and/or saved to a thumb drive for charting at the LifeSpan Fitness Club website.
- Intensity Options: Preset workouts can be used at three challenge levels as well as with differing inclines.

- Tablet Holder: Dock your tablet or smartphone on the console for easy viewing during workouts.
