NordicTrack T Series: the home treadmill America buys most
The NordicTrack T Series is one of the most popular home treadmills on Amazon, with more than 32,000 ratings. It comes in five models, from the simple T5 to the T16 with a 16-inch touchscreen, and works with iFIT trainer-led workouts.
Below: which model to buy, what buyers love and complain about, whether you need iFIT, and how it compares with ProForm and other rivals.
The short answer
Our verdict: a sturdy, trusted treadmill for walking and running at home. The T6.5s is the best value for most people, and the T10 is the pick for faster runners.
Assembly is the most common complaint, so plan for two people or professional setup.
Buy it if
- You want a big-brand folding treadmill for walking and running.
- You like trainer-led workouts that control the incline for you.
- You want a choice of screens and speeds in one family.
Skip it if
- You want to avoid a monthly membership for smart workouts.
- You need more than 10% incline on a budget model.
- You have no help for a heavy assembly.
Pick your T Series: T5, T6.5s, T7, T10 or T16
All five models are sold on one Amazon listing. Tap a model to open that exact treadmill. The main differences are the screen, top speed, incline and cushioning.
T Series models compared
| Model | Screen | Top speed | Incline | Cushioning | Best for |
|---|---|---|---|---|---|
| T5 | LCD + device shelf | 10 mph | 0–10% | KeyFlex | Walkers on a budget |
| T6.5s | LCD + device shelf | 10 mph | 0–10% | KeyFlex | Most homes (best value) |
| T7 | LCD + device shelf | 10 mph | 0–10% | SelectFlex (adjustable) | Joint comfort |
| T10 | 10″ touchscreen | 12 mph | 0–12% | SelectFlex | Runners who want a screen |
| T16 | 16″ touchscreen | 12 mph | 0–12% | SelectFlex | Big-screen iFIT classes |
Our pick: the T6.5s for most people. It has the features that matter, it folds, and it is the most-reviewed model. Choose the T10 if you run faster than 10 mph or want a built-in touchscreen for iFIT classes.

Do you need an iFIT membership?
No, but it changes the experience. Without a membership, you get manual controls for speed and incline and a few built-in workouts on the LCD models. With iFIT, trainers lead walks, runs and hikes, and the treadmill changes its own speed and incline to match. On the T10 and T16, classes play on the built-in touchscreen. On the T5, T6.5s and T7, you follow them on your own phone or tablet.
ActivePulse uses a Bluetooth heart-rate monitor (sold separately) to keep you in your target zone by adjusting speed and incline automatically. It needs an iFIT membership.
Is the T Series good for walking?
Yes. It is one of the best choices for incline walking at home. All models reach at least 10% incline, which is enough for popular workouts like 12-3-30 on the T10 and T16 (12% incline). Our treadmill pace and incline calculator shows calories and flat-ground effort for any speed and incline.
Is it good for running?
For easy and steady runs, yes. The T5, T6.5s and T7 top out at 10 mph (a 6-minute mile), which covers most home runners. If you do fast intervals or sprints, choose the T10 or T16 with 12 mph.

Assembly and space tips
- The box is very heavy (around 200 lb for the T6.5s). Have two people, and open it in the room where it will live.
- Leave at least 2 ft on each side and about 6.5 ft behind the treadmill for safety.
- Measure your ceiling: your height while running plus the deck height and incline must fit comfortably.
- Put a treadmill mat underneath to protect floors and cut noise.
- Lubricate and check the belt as the manual says.
Is the NordicTrack T Series worth it?
Yes, for most home walkers and runners. You get a sturdy, folding treadmill from a big brand with a strong parts network, real incline, and optional smart training. The trade-offs are a heavy, slow assembly and an extra monthly cost if you want iFIT classes. If you want a steeper incline for walking or a smaller frame, look at the alternatives above.
NordicTrack T Series 5 review: is the cheapest model enough?
The T5 is the entry model. It has the same 0 to 10 mph speed and 0 to 10% incline as the T6.5s, an LCD display with a device shelf and KeyFlex cushioning. For walkers and easy joggers, that covers almost everything. The T6.5s is often only a little more and is the most-reviewed model, so compare both prices on the day you buy. Choose the T5 if every dollar counts and you mostly walk.
T6.5s vs T7: is adjustable cushioning worth it?
The T7 adds SelectFlex cushioning, which you can set from soft to firm. Softer cushioning is kinder to knees and hips when walking. Firmer cushioning feels closer to running on the road. If you have joint pain or share the treadmill with someone who runs, the T7 is worth a look. Otherwise, the T6.5s gives the same speed and incline for less.
T10 vs T16: which screen size?
Both have 12 mph top speed and 12% incline. The only big difference is the screen: 10 inches on the T10 and 16 inches on the T16. If you plan to follow iFIT classes every day, the bigger screen is more immersive. If you mainly watch your own shows on a tablet, save money with the T10.
Easy workouts to start with
- Brisk walk: 3 to 3.5 mph, 0 to 2% incline, 20 to 30 minutes.
- Incline walk: 3 mph at 8 to 10% incline for 20 minutes. Build to 12% on the T10 or T16.
- Walk-run intervals: 1 minute running, 2 minutes walking, repeat 8 times.
- Steady run: a comfortable pace at 1% incline for 20 to 40 minutes.
Care and maintenance
- Wipe the deck and belt after sweaty workouts.
- Check belt tension and centering every few months.
- Lubricate the belt when the manual says, usually every few months with regular use.
- Vacuum under and around the treadmill to keep dust out of the motor.
- Register your warranty right after delivery.
Treadmill vs walking pad: which do you need?
A walking pad is a slim, low treadmill made for walking, often under a desk. It is cheaper and easier to store, but most have little or no incline and lower top speeds. A full treadmill like the T Series has handrails, a longer deck, real incline up to 10 or 12% and speeds for running. If you only want to walk while working, a walking pad is enough. If you want incline workouts or running, choose the T Series.
Power and placement
Treadmills draw a lot of power. Follow the outlet and surge-protection advice in the NordicTrack manual, and avoid long extension cords. Place the treadmill on a flat, solid floor, away from walls and furniture, and keep the cord where you will not trip on it. A treadmill mat under the frame helps with noise, vibration and floor protection.
How to use incline for weight loss
Walking on an incline burns far more calories than flat walking at the same speed, with less impact than running. A simple plan: start at 3 mph and 4% incline for 20 minutes, then add 1% each week until you reach 10%. On the T10 or T16, you can go up to 12%. Our treadmill calculator shows the calories for each setting.
Before you buy: a quick checklist
- Measure the room, including the space behind the treadmill and the ceiling height.
- Decide whether you want a screen built in (T10, T16) or will use your own tablet.
- Check the delivery and assembly options at checkout.
- Decide whether you will pay for iFIT, and budget for it.
- Check the weight limit for the model you choose in the listing.
Who the T Series suits best
- Walkers: the T5 or T6.5s, with plenty of incline for a brisk uphill walk.
- Couples with different needs: the T7, so each person can set the cushioning they like.
- Runners: the T10, for 12 mph and 12% incline.
- Class lovers: the T16, for the biggest built-in screen.
Whichever model you choose, take it slowly for the first two weeks. Short, easy sessions help your legs adapt to the belt and help you learn the controls before you try faster workouts.
Is the T Series good for tall or heavy users?
Taller runners should look at deck length and the top models. A longer stride needs more belt, and the T10 and T16 are the better fit for runners over about 6 ft who run fast. Heavier users should check the weight limit for their exact model in the listing and choose a model well above their weight, which helps the motor and belt last longer.
