Cardirun TM037 FitScore
FitScore rates each treadmill on structured product data, weighted for one buying intent. The Cardirun TM037 is bought mainly for walking while you work, so this review uses the same weights as our best folding treadmill with desk guide, where it ranks #3 with the same score. Practicality counts most (50%), then durability (15%), with performance, comfort and affordability at 10% each and features at 5%, because a desk treadmill has to fit, store and move easily before anything else.
FitScore for Desk Walking
How this FitScore was calculated
This FitScore combines 6 category scores using the weights of the buying intent above.
- Practicality (64.0): light, folds to about 5 inches and rolls under a desk or bed.
- Durability (55.0): alloy steel frame, with a 1-year warranty.
- Affordability (100.0): one of the most budget-friendly ways to add a desk walking pad.
- Performance (70.0): fine for desk-speed walking, limited to 6.2 mph and a manual 10% incline.
- Comfort (38) and features (41): short belt and a basic LED display.
Design and Build Quality
The TM037 uses an alloy steel frame and weighs about 41.6 lb. Assembled, it is about 43 inches long and 21 inches wide, small enough to sit under most standing desks.
Owners describe it as sturdy and stable for daily walks. Several reviewers note that the handlebar is too low for taller adults, so plan to walk hands-free at your desk if you are tall.
Bottom line: light and stable for daily desk walking.
Walking Performance
The TM037 has two modes. Walking mode runs from 0.6 to 3.8 mph, which suits slow desk walking, and running mode goes up to 6.2 mph for brisk walks and a light jog.
Cardirun lists a 3.0 HP motor. Independent analysis of closely related hardware suggests that figure is a peak rating, with continuous output well below it, which matters little at desk-walking speeds but means this is not a running machine.
Bottom line: built for walking while you work, not for running.
Walking Belt and Cushioning
The belt measures 36 × 16 inches. That is enough for a natural walking stride, but it feels short at the top of the running mode.
Eight silicone shock absorbers soften each step. A few owners of closely related models mention the belt shifting over time, so check tracking regularly.
Bottom line: comfortable for walking, short for jogging.
Incline and Programs
The listing describes a 10% manual incline, a grade that makes easy walks noticeably more demanding. You set it before you start rather than adjusting it mid-walk.
No built-in workout programs are listed. For hill walking, the Trisomy D2 or Trisomy HSM-T12C1 offer much steeper incline.
Bottom line: a mild grade, not a hill trainer.
Display, App and Connectivity
An LED display shows your basic stats, and the TM037 connects over Bluetooth to compatible fitness apps on your phone.
There is no large screen and no subscription to pay for, which is ideal if you are walking while working at a computer.
Bottom line: simple, with no ongoing costs.
Footprint, Folding and Noise
Folded, the TM037 is about 43 × 21 inches and only about 5 inches tall. Owners like that it rolls easily and slides under a bed or desk.
Owners find it surprisingly quiet for daily walks, which matters if you take calls while you walk. A mat helps on hard floors.
Bottom line: one of the easiest walking pads to hide away.
Setup, Warranty and Support
The listing does not detail assembly, but at about 41.6 lb and 43 inches long, the TM037 is easy for one person to roll into place once it is unboxed.
The warranty covers the frame, motor, parts and labor for 1 year. A few owners of closely related models report motor problems after several months, so register the warranty and keep your proof of purchase.
Bottom line: easy to live with, with short coverage.

Alternatives to the Cardirun TM037
Steeper incline, longer warranty: Choose the Trisomy HSM-T12C1 if you want 12% incline, a 350-lb rating and a 2-year warranty in a 47-lb pad.
Top pick for desks: Choose the Trisomy D2 (FitScore 72.9) if you want 15% incline, a 450-lb rating and a 2-year warranty.
Faster with a longer belt: Choose the THERUN 2-in-1 Treadmill X2 Starter if you want up to 7.6 mph on a 40-inch belt and stay under 265 lb.
Biggest deck: Choose the WalkingPad R3 Hybrid+ if you want a 17.3 × 47.2-inch belt and up to 7.5 mph, and you do not need incline.
Final Verdict
The Cardirun TM037 is a smart pick if you want a light, quiet walking pad that disappears under a desk or bed. The short belt, mild manual incline and 1-year warranty keep it in the walking category. If you want steeper incline and longer coverage, the Trisomy D2 is the better fit.
