Frequently Asked Questions: Treadmills

Not at all. A treadmill can be used for walking, jogging, running, and incline training. Many people even add treadmill walking to their HIIT routines or use it for active recovery days. For example, a NordicTrack treadmill paired with an iFIT walking program can deliver low-impact, calorie-burning workouts that go far beyond just running.

Higher-end treadmills usually come with upgraded features. These include HD touchscreens, SmartAdjust technology, incline/decline ranges, and cushioned decks that protect your joints. Models like the Commercial 1750 or X16 Incline Treadmill justify their price with more power, durability, and immersive iFIT training options. Some advanced treadmills also qualify for wellness programs. Learn more in our FSA Eligible Treadmill Guide.

Yes, running outdoors is free. However, consistency can be tough. Bad weather, safety concerns, or time constraints often get in the way. The good news is that a treadmill ensures you can train safely at home, anytime. Even better, with incline treadmill workouts and iFIT global runs, you can recreate outdoor conditions without leaving your house.

For more detail on incline benefits, see our guide on why incline treadmill training works better than flat walking.

Yes. In fact, treadmills provide a smoother, safer surface that helps reduce the risk of injury from potholes, traffic, or uneven terrain. To closely match outdoor road running, set the incline to about 1–1.5 percent. This feature is standard on all NordicTrack treadmills, including the Commercial 2450.

Yes. Walking at a slow pace on a treadmill desk¹ lets you answer calls, type, or attend virtual meetings while moving. Research suggests this can improve focus and creativity compared to sitting all day. It might take a short adjustment period, but once you’re used to it, you’ll wonder why you didn’t start sooner.

A treadmill balances your training by blending steady-state cardio with incline intervals, recovery walks, and HIIT. When paired with iFIT’s global workouts, your treadmill can automatically adjust incline and speed to simulate outdoor terrain, giving you a more dynamic and engaging session. If you’re comparing options, check out our breakdown of cardio machines to see how treadmills stack up against ellipticals, rowers, and bikes.

No special shoes are required. Any supportive running or training shoes with good cushioning will work. Unlike outdoor routes, treadmills protect you from debris like rocks or glass, making them a safer and more comfortable option.

Beginners should start with 15–20 minutes of treadmill walking at a comfortable pace, then gradually increase duration as fitness improves. Adding small incline intervals can boost calorie burn without overexertion.

A 1–2% incline mimics outdoor road conditions, while higher inclines (5–12%) increase calorie burn and engage more muscles. For maximum results, alternate between flat walking and incline intervals, or try structured programs like the 12-3-30 treadmill workout.

Not necessarily. Many NordicTrack treadmills fold vertically for storage, making them practical for apartments or small home gyms. If space is limited, look for models with SpaceSaver design and EasyLift Assist.
