It's a solid one, and the brand stores are where it shows. BowFlex is running a Labor Day sale with $400 off every treadmill in the range, Horizon has the 7.0 AT at $1,099 against $2,100, and SOLE has the F63 at $1,099.99. January is still the biggest window of the year because retailers price for resolutions, but a $1,000 cut on a Horizon isn't something you should wait out.
The number that decides whether a treadmill suits you isn't the price, it's the belt. Walking wants 16 to 20 inches wide by 50 to 55 long; running wants a full 20 by 60, because your stride lengthens as you speed up and a short deck makes you shorten it. Motor power follows the same logic: about 1.5 to 2.0 CHP for walking, 2.0 to 2.5 for jogging, and 2.5 to 3.0 or more for running, with 3.0 to 4.0 the sensible range if you sprint. That's why a walking pad with a 40-inch belt is a genuinely good desk machine and a bad running machine.

The full range, from walking pads that slide under a desk to full-size machines with a proper running deck. Check the belt dimensions on any listing before the price, because the two ends of this category look similar in photographs and behave nothing alike underfoot.
When Treadmills Actually Go On Sale
Fitness equipment is priced against motivation, which makes January the loudest window and the rest of the year quietly more interesting.
| When | What to expect |
|---|---|
| January, New Year | The biggest window of the year. Retailers know fitness is on everyone's mind and clear inventory into it, so the discounts are wide and the selection is at its best. It's also when delivery slots get tight. |
| Black Friday and Cyber Monday | Deep, and the week the brands add extras rather than just cutting prices: free shipping, free mats, extended trials and bundled memberships all show up here. |
| Right now, over Labor Day | Better than usual this year. BowFlex has $400 off its whole treadmill line through mid-September and Horizon is more than $1,000 off the 7.0 AT. Worth taking if you want to be running indoors before the weather turns. |
| Prime Day, July and October | Reliable, and occasionally dramatic on the budget end. Discounts of around 50% have shown up on individual models, though usually on the folding and walking-pad side rather than on full-size machines. |
| When a model gets replaced | A treadmill is a motor, a deck and a screen, and the first two barely change year to year. The outgoing model is often the same machine with an older tablet bolted to it. |
| Late spring into summer | The dead zone. People run outside, demand collapses, and rather than discounting, retailers simply carry less. Fewer models, fewer offers, longer waits. |
What Actually Counts as a Good Treadmill Deal
Price these against belt size and motor rather than against the screen, because that's what determines whether the machine can do what you bought it for.
- Walking pad under $200. A 40-inch belt, 1.5 to 2.0 CHP, folds flat under a desk or a sofa. Sunny has a compact manual at $199.99, and the powered pads sit just above that.
- Folding treadmill under $600. Enough deck for jogging and a fold that actually helps. Sunny's Pace 500 with auto incline is $599.99, which is roughly where this band tops out.
- Full-size running treadmill under $1,200. A 20 by 60 inch belt and 3.0 CHP or better. The SOLE F63 is $1,099.99 and the Horizon 7.0 AT is $1,099 against $2,100, which is the standout number on this page.
- Connected treadmill under $900. BowFlex has the T6 at $899 against $1,299 with a lifetime frame and motor warranty and no membership needed to use it.
- Curved manual under $2,200. A different machine entirely, with no motor and no top speed. The SOLE C80 is $2,199.99 against $2,399.99, which is about as low as this category goes.
Shop Folding Treadmills
The compromise most people actually want, as long as you know which kind you're getting. A true folding treadmill lifts the deck vertically to free up floor space and still gives you a usable running belt underneath. What gets sold as folding at the cheap end is often a walking pad with a hinge, which folds beautifully and has nowhere near the deck length to run on. Check the belt dimensions and the folded footprint separately, because a listing will happily give you one and not the other.
Shop Walking Pads and Under-Desk Treadmills
The fastest-growing corner of this category, and genuinely useful for what it does. A walking pad is a slim motorized belt with no handrail, built for 1 to 4mph under a standing desk, and the good ones disappear under a sofa when you're done. Belts run around 40 to 45 inches, which is fine for walking and unsafe for anything faster. Treat top-speed claims of 6mph as marketing: you wouldn't want to run on a 40-inch deck with nothing to hold.
Shop Incline Treadmills
Incline is the cheapest way to make a treadmill harder without making it faster, which is why it's the feature worth paying for. Walking at 12% raises your heart rate into the same range as a slow run while keeping the impact low, and that suits knees, ankles and anyone coming back from an injury. Two things to check: whether the incline is motorized or set by hand, since a manual pin means you'll never change it mid-workout, and whether the frame is stable at the steepest setting.
Shop Manual and Curved Treadmills
No motor, no plug, no top speed set by a machine. A curved manual treadmill is driven entirely by your stride, so it speeds up when you push and stops when you do, which makes it excellent for intervals and unforgiving for everything else. It burns noticeably more energy at the same pace and it teaches a better footstrike. Flat manual treadmills at the budget end are a different thing altogether and are hard work in the wrong way, because the belt drags rather than rolling.
Where to Shop Treadmills
Worth checking beyond Amazon, because the brands run their own holiday sales here and they're the only place the belt dimensions and motor ratings are listed properly.
How to Pick the Right Treadmill
Buy the belt, not the badge. Walking needs 16 to 20 inches wide by 50 to 55 long. Running needs a full 20 by 60, because your stride opens up as you speed up and a short deck quietly forces you to shorten it. This single specification separates a machine you'll use from one you'll resent, and it's usually buried at the bottom of the listing.
Match the motor to what you'll actually do. About 1.5 to 2.0 CHP covers walking, 2.0 to 2.5 covers jogging, and 2.5 to 3.0 or more is what running asks for, with 3.0 to 4.0 the range if you sprint. Continuous horsepower is the number that matters, not peak, and an underpowered motor pushed hard is the most common way a cheap treadmill dies.
Price the membership before you price the machine. A connected treadmill with a built-in touchscreen from NordicTrack, ProForm or Freemotion runs on iFIT Pro at $39 a month, which is $468 a year on top of the purchase. That can be worth it if you use guided workouts. If you won't, buy a machine that works fully without one, which BowFlex advertises explicitly.
Pay for incline rather than for top speed. Almost nobody uses the upper half of the speed range on a home treadmill, and almost everybody would benefit from a steeper incline. Walking at 12% gets your heart rate up like a slow run with far less joint impact. Check that the incline is motorized, because a manual pin means you'll set it once and never touch it again.
Measure the room, including the ceiling. A full-size treadmill needs floor space plus clearance behind it, and running on a deck raises your head by several inches, which matters in a basement. Folding helps with storage but not with the space you need while it's running. Work this out before you order, not after it arrives on a pallet.

The Bottom Line
Decide what you'll actually do on it, then buy the belt and the motor that match: 20 by 60 inches and 3.0 CHP if you run, and a walking pad if you want to move while you work. Those two machines aren't versions of each other. Price any membership into the total before you compare, because $39 a month is $468 a year and a treadmill that needs one isn't as cheap as it looks. Then spend on incline rather than top speed, since that's the part you'll actually use. January is still the biggest window of the year, but BowFlex at $400 off across the line and Horizon at more than $1,000 off the 7.0 AT are worth taking now.
