Short answer
CHP means continuous horsepower: the power a treadmill motor can deliver steadily for a whole workout without overheating. Peak horsepower is a brief maximum and always reads higher. For walking, look for about 2.0 to 2.5 CHP; for jogging, about 3.0 CHP; for daily running, 3.0 to 4.0 CHP. Add about 0.5 CHP for heavier users.
Key takeaways
- CHP is the power a treadmill motor can sustain for a full workout.
- Peak horsepower is a brief maximum and always reads higher.
- Walkers need about 2.0 to 2.5 CHP; runners about 3.0 to 4.0 CHP.
- Heavier users and daily runners should add about 0.5 CHP.
- Judge the motor together with speed, deck size, capacity and warranty.
- Lifetime motor coverage on Horizon, Sole and XTERRA TR75 models is a useful signal.
Treadmill listings lead with motor power, but the number is easy to misread. Two machines can both claim “3.5 HP” and feel completely different under a heavy runner, because one rating is continuous and the other is a short peak. Knowing the difference is the quickest way to avoid a motor that strains, overheats or wears out early.
This guide explains what CHP means, how it differs from peak horsepower, how to read the motor line on a spec sheet and what motor size fits walking, jogging and running at different body weights. The motor ratings come from the models in our reviews, and the sizing advice matches our treadmill buying guide.
What CHP Means on a Treadmill
CHP stands for continuous horsepower. It describes how much power the motor can deliver steadily, minute after minute, for the length of a normal workout without overheating. Some brands call it continuous duty or a treadmill-duty rating. It is the number that tells you how the treadmill will behave during a 45-minute run, not during the first few seconds.
The motor turns the front roller, which moves the belt under your feet. Every footstrike briefly slows the belt, and the motor has to push back to hold your set speed. A motor with more continuous power handles that load with less effort, so the belt feels smoother and the motor runs cooler. Our Horizon 7.4 AT review is a good example of a listing that states the rating clearly as 3.5 CHP.
CHP vs Peak Horsepower
Peak horsepower is the most the motor can produce for a brief moment. It always reads higher than continuous power, sometimes much higher, which is why it appears so often in marketing. A peak figure tells you little about how the motor copes with a long session.
Many listings, especially for walking pads and compact treadmills, just say “HP” without saying which kind. Independent testers of the THERUN T15 report that its 3.5 HP figure is a peak rating with lower continuous output, and found the belt slow to reach set speeds. Our Cardirun TM037 review notes the same likely pattern on that desk treadmill, which matters little at walking speeds.
When a listing gives only “HP”, look for the CHP figure in the manual or spec sheet, or ask the seller. If you cannot find it, judge the motor alongside the deck size, top speed, weight rating and motor warranty rather than on the headline number alone.
| Continuous horsepower (CHP) | Peak horsepower | |
|---|---|---|
| What it measures | Power sustained for a full workout | Brief maximum output |
| Typical use in listings | Mid-range and premium treadmills | Walking pads, compact and budget models |
| Reads higher? | No | Yes, on the same motor |
| Useful for comparing? | Yes | Only with other peak figures |

Watch out: A walking pad with a big HP number is not a running treadmill. Short belts and low top speeds limit it no matter what the motor claims.
What Motor Size Do You Need?
Match the motor to your most demanding regular use, not your average day. Walkers need less continuous power than runners, and steady incline walking sits in between. The table uses the same ranges as our treadmill buying guide, with examples from our reviews.
These are practical ranges, not strict rules. A motor near the top of the range for your use usually runs quieter and cooler because it is working well below its limit, which is one reason the top models in our best quiet treadmill guide use motors of 2.6 to 3.6 HP rather than the smallest options.
| Main use | Suggested motor | Example from our reviews |
|---|---|---|
| Walking, under 3.5 mph | 2.0–2.5 CHP | Horizon T101 (2.5 HP) |
| Brisk and incline walking | 2.5–3.0 CHP | NordicTrack T Series 7 (2.6 HP) |
| Jogging several times a week | 3.0 CHP | Schwinn Fitness 815 (3.0 HP) |
| Daily running and intervals | 3.0–4.0 CHP | Horizon 7.4 AT (3.5 CHP) |
| Heavy runners and high mileage | 4.0 HP and up | Sole TT8 (4.0 HP) |
How User Weight Changes the Motor You Need
A heavier runner puts more load on the belt with every stride, and the motor has to work harder to hold speed. Daily use adds heat and wear in the same way. As a rule of thumb, add about 0.5 CHP to the range for your use if you are a heavier user, run most days or share the treadmill with several people.
Motor power works together with the frame and deck. A strong motor on a light frame with a narrow belt still feels unstable. That is why our best treadmill for heavy people and best treadmill for heavy runners guides are led by models with 3.5 HP and up, 22 × 60-inch decks and 350- to 400-lb ratings. Our best treadmill 300 lb capacity guide covers models rated for 300 lb and up.
- Walking, heavier user: aim for about 2.5 to 3.0 CHP.
- Jogging, heavier user: aim for about 3.5 CHP.
- Running, heavier user: aim for about 3.5 to 4.0+ CHP with a 22-inch-wide deck.

Check Price on AmazonHow to Read the Motor Line on a Spec Sheet
Read the motor line together with the rest of the spec sheet. The motor rating only makes sense next to the top speed, deck size and weight capacity it is meant to support.
Look for the word continuous or the letters CHP. If the listing only says HP, treat it as unconfirmed. Check that the top speed matches your use: 10 mph is plenty for walking and jogging, while runners usually want 12 mph. Then compare the deck: 20 × 55 inches for walking, 20 × 60 inches for running and 22 inches wide for heavier users or a wide gait. Our treadmill cushioning guide covers the deck itself.
Brushless motors appear on some newer compact treadmills and walking pads, such as the WELLFIT TM029 with a listed 5 HP brushless motor and a 20 × 50-inch deck. Brushless designs can be efficient and quiet, but the motor type does not change the need to confirm whether a rating is continuous or peak.
- Is the rating labeled continuous (CHP) or not specified?
- Does the top speed fit how you train?
- Is the deck long and wide enough for your stride?
- Does the weight capacity leave at least a 50-lb margin?
- How long is the motor warranty?
Motor Warranty: The Second Signal
Motor warranty length is a useful hint about how the manufacturer expects the motor to hold up. In our reviews, Horizon models such as the Horizon 7.0 AT, Sole models such as the Sole F65 and the XTERRA TR75 list lifetime motor coverage, and Schwinn’s 815 and SFT4.3 list 10 years. Many NordicTrack T Series and ProForm Carbon models list 1 to 2 years.
A long warranty is not a guarantee, and terms differ: some cover parts but not labor, and many exclude commercial use or use above the rated weight. The FTC explains how to read a warranty before you buy. Regular care also protects the motor; a dry deck or loose belt makes it work harder. Our treadmill maintenance guide and treadmill lubrication guide cover both.
| Model | Listed motor | Top speed | Motor warranty |
|---|---|---|---|
| Horizon T101 | 2.5 HP | 10 mph | Lifetime |
| NordicTrack T Series 7 | 2.6 HP | 10 mph | 2 years |
| Horizon 7.0 AT | 3.0 HP | 12 mph | Lifetime |
| Sole F65 | 3.0 HP | 12 mph | Lifetime |
| Horizon 7.4 AT | 3.5 CHP | 12 mph | Lifetime |
| Sole TT8 | 4.0 HP | 12 mph | Lifetime |
| NordicTrack Commercial 2450 | 4.25 HP | 14 mph | Lifetime |

Check Price on AmazonChecklist Before You Buy
- Confirm whether the listed motor rating is continuous (CHP) or peak.
- Match the motor to your most demanding regular workout.
- Add about 0.5 CHP if you are a heavier user or run most days.
- Check that the top speed and deck size fit the motor’s intended use.
- Leave at least a 50-lb margin on weight capacity.
- Compare motor warranty length across your shortlist.
- Read the warranty for weight and commercial-use exclusions.
- Plan regular lubrication and belt checks to protect the motor.
Common Mistakes to Avoid
- Comparing a peak HP figure with another brand’s CHP figure.
- Buying a walking pad for running because of a high HP number.
- Choosing a motor for average use when you also run intervals.
- Ignoring user weight when sizing the motor.
- Overlooking a short motor warranty on an otherwise strong spec sheet.
- Skipping deck lubrication, which makes any motor work harder.
The Bottom Line
- Continuous horsepower (CHP) is what the motor sustains; peak horsepower is a short burst and can read far higher on the same motor.
- Many listings just say “HP”; testers found the 3.5 HP rating on the THERUN T15 is a peak figure with lower continuous output.
- In our reviews, walking treadmills list about 2.5 to 2.6 HP, mainstream running models 3.0 to 3.5 HP and heavy-duty decks 4.0 to 4.25 HP.
- Heavier users and daily runners load the motor more, so add about 0.5 CHP to the usual range.
- Motor warranty length is a useful second signal: Horizon, Sole and the XTERRA TR75 list lifetime motor coverage.

Frequently Asked Questions
CHP means continuous horsepower, the power the motor can deliver steadily for a full workout without overheating. It is the most useful motor number for comparing treadmills.
Yes, for walking and light jogging. Regular joggers and runners should look for 3.0 CHP or more.
For most runners, yes, especially with a 20 × 60-inch deck. Heavier or high-mileage runners should consider 3.5 to 4.0 CHP.
CHP is a continuous rating. Plain HP may be continuous or peak; if the listing does not say, treat it as a possible peak figure and check the manual.
Often, because a motor working below its limit runs cooler and smoother. Belt, deck, floor and maintenance also affect noise.
Add about 0.5 CHP to the range for your use: about 2.5 to 3.0 CHP for walking and 3.5 to 4.0 CHP for running, with a 22-inch-wide deck.
Rarely. Many list a single HP figure that testers sometimes find is a peak rating, so compare walking pads by belt size, top speed and weight capacity.
