The Treadmill Buying Decision
A treadmill is often the single biggest purchase in a home gym. With prices ranging from $400 to $5,000+, making the right choice matters. This guide breaks down every factor you should consider.
Motor Power: CHP Matters
Treadmill motors are rated in Continuous Horsepower (CHP), which measures sustained output rather than peak power. Here is what to look for:
- Walking only: 2.0 CHP is sufficient
- Jogging and light running: 2.5-3.0 CHP
- Serious running: 3.0-4.0 CHP
- Heavy use or large users: 3.5+ CHP
The NordicTrack Commercial 1750 offers 3.5 CHP, making it suitable for all user types. Budget models like the XTERRA TR150 at 2.25 HP are better suited for walking and light jogging.
Belt Types: Traditional vs Slat
Traditional belts are the most common and work well for most users. Slat belts, like the one on the Peloton Tread, consist of individual rubber slats that provide better cushioning and a more natural running surface. Slat belts last longer but cost significantly more.
Incline and Decline
Incline training dramatically increases calorie burn and engages different muscle groups. Look for:
- Basic: 0-10% incline (entry-level machines)
- Standard: 0-15% incline (most mid-range treadmills)
- Advanced: -3% to 15% incline with decline capability
Decline capability is rarer but valuable for training downhill running. The NordicTrack 1750 offers -3% decline.
Screen and Connected Features
Modern treadmills increasingly include touchscreens and app subscriptions:
- No screen: Budget models under $600, use your own device
- Basic LCD: Shows speed, distance, time, calories
- 7-10 inch touchscreen: iFIT or similar guided workouts
- 14-24 inch touchscreen: Full streaming class experience
Consider whether you will actually use guided workouts. If you prefer watching TV or listening to music while running, a large built-in screen adds cost without value.
Folding vs Non-Folding
Folding treadmills save significant floor space when not in use. Most mid-range treadmills fold, including the Sole F80 and NordicTrack 1750. Premium models like the Peloton Tread typically do not fold due to their heavier construction.
Weight Capacity
Always check the maximum user weight rating. Budget machines typically support 250-275 lbs, mid-range 300-325 lbs, and premium models 300-400 lbs. Choose a machine rated at least 50 lbs above your weight for optimal longevity.
Running Surface Size
Standard home treadmill belts are 20 inches wide and 55-60 inches long. Taller runners or those with longer strides should look for 22-inch width and 60+ inch length.
Noise Level
If you live in an apartment or plan to run while others sleep, noise matters. Magnetic resistance and slat belts are quieter than traditional motors and belts. The Peloton Tread is notably quiet, while budget treadmills tend to be louder.

Final Advice
Test before buying if possible. Visit a fitness equipment store to try different models. Pay attention to how the belt feels underfoot, how stable the handrails are, and whether the console is intuitive. Your treadmill should feel natural and motivating, not like a chore.
