How to choose
- Incline Range. Look for a treadmill that offers at least a 12% incline for noticeable terrain variety. Some models, like the NordicTrack Commercial 1750, also include decline to simulate downhill running, which reduces joint impact.
- Motor Power. A motor rated 2.5 to 3.5 CHP (continuous horsepower) is ideal for regular incline use. Higher CHP ensures the motor doesn't overheat or slow down during steep inclines, especially for runners.
- Belt Size. A belt width of at least 20 inches and length of 55 inches is adequate for walking. For running, aim for 22×60 inches to allow natural stride length. Taller users should prioritize longer belts.
- Cushioning System. Incline running increases impact on knees and ankles, so cushioning is essential. Brands like NordicTrack and Peloton offer variable cushioning that can be adjusted for a firmer or softer feel.
- Foldability and Storage. If space is limited, choose a treadmill that folds, either vertically or with an EasyLift system. Check the folded dimensions and weight, as heavier models may require two people to move.
Frequently asked questions
What is the best incline percentage for a treadmill?
For most users, a 12% to 15% incline is sufficient for effective hill training. Some advanced models offer up to 40% incline, but 15% is a practical maximum for regular workouts.
Do incline treadmills burn more calories?
Yes, walking or running on an incline significantly increases calorie burn compared to flat running. A 5% incline can boost calorie expenditure by about 50% over the same duration on flat terrain.
Is a decline treadmill worth it?
Decline settings simulate downhill running, which engages different muscle groups and can reduce impact. They are useful for variety and rehab, but not essential for most users.
Can I use an incline treadmill for walking?
Absolutely. Incline treadmills are excellent for walking, as you can dial in a steep grade for a challenging low-impact workout. Many walkers prefer models with a decline option for added intensity.
How much space does an incline treadmill need?
Plan for at least 6×4 feet of floor space, plus extra room around the sides for safety. Foldable models can reduce the footprint when stored, but still require clearance during use.
What brand makes the most durable incline treadmill?
NordicTrack and Horizon are consistently rated as durable brands for incline treadmills. The Peloton Tread+ has premium build but at a high cost. Sunny Health & Fitness offers budget options with adequate durability for moderate use.
The verdict
The NordicTrack Commercial 1750 stands out as the best overall incline treadmill for its unmatched -3% to 40% range and powerful motor. For those without a subscription budget, the Horizon 7.0 AT offers excellent value with no lock-in. If premium is your priority, the Peloton Tread+ delivers top-tier build and immersion, despite its limited 15% incline.
