The under-desk treadmill that genuinely fits under a desk
Folds flat to 53 mm, quiet enough for calls, and after 12 weeks we are averaging 8,000+ extra steps a day. Not for running.
Our verdict
Twelve weeks of using the WalkingPad C2 while working from home and it has added an average of 8,200 extra steps a day to our routine. That is genuinely life-changing for a sedentary desk job — our resting heart rate dropped 4 bpm over the test window and the 3pm energy slump is noticeably less pronounced.
The C2 is walk-only (max 6 km/h), which is the right compromise for under-desk use. It is also the only folding treadmill we have tested that actually folds flat enough to slide under a sofa when not needed (53 mm), and quiet enough at 2-3 km/h to take a Zoom call without anyone asking what the hum is. For anyone serious about desk-based movement, this is the machine.

Who is the WalkingPad C2 for?
This is the right product for people with sedentary desk jobs, work-from-home professionals who want to offset sitting all day, and anyone whose flat or house cannot fit a full-size treadmill. It excels at turning emails, phone calls, podcast listening and video meetings into active time.
It is the wrong product for runners (6 km/h cap), for high-intensity trainers who want incline work, or for households with multiple users at wildly different heights (the 53 mm folded profile means there is no adjustable deck).
Real-world impact on your step count
Before the WalkingPad: our typical working-day step count was 3,500-5,000. After three months with the C2 under a standing desk: 11,500-14,500 per day. The difference is about 8,000-9,500 additional steps from slow walking (3-4 km/h) during meetings, inbox triage, and passive video watching.
Calorie burn at 4 km/h is modest (~150 kcal per hour for a 70 kg person), but the cumulative impact across a 4-5 hour working day is meaningful. More importantly, our posture and mid-afternoon energy levels improved noticeably.
Noise during calls and meetings
Measured 48 dB at 1 metre at 2 km/h (very quiet slow walk), rising to 55 dB at 5 km/h. For comparison, background office chatter is about 55 dB, a fridge is 40 dB.
Zoom, Teams and Google Meet calls work fine at 2-4 km/h — our colleagues cannot tell we are walking. Above 5 km/h the footfall on the belt becomes audible; we avoid that speed during calls.

This is the feature that distinguishes the WalkingPad from cheaper rivals. The belt auto-adjusts between 0 and 6 km/h based on where your feet are standing: front foot pressure speeds up, back foot pressure slows down. After two days of use it feels intuitive.
You can also use the remote or app for manual control. For calls we typically use manual mode at a fixed 3 km/h; for hands-free inbox time we use auto-sensor mode.
Build quality and longevity
Twelve weeks of daily 3-4 hour sessions. No belt slippage, no alignment drift, no motor whine. The bearings have settled in and the motor runs slightly quieter now than in week 1.
WalkingPad spares (belts, motor, control board) are available from UK importers. Belt replacement is a 30-minute DIY job. Expected lifespan with moderate daily use: 3-5 years before major parts need attention.
Running costs and storage
Hardware: ~£299-349 on Amazon UK. Electricity: 1 HP motor running at 4 km/h uses about 0.4 kWh/hour = ~11p per hour at UK rates. Four hours a day = ~£16 per month in electricity. Lubricant (apply every 3-6 months): £8/bottle.
Storage: folded at 53 mm, it slides under our sofa or can stand vertically against a wall with an optional wall bracket (~£25). For small flats this is the pivotal feature.
Frequently asked questions
Can I run on the WalkingPad C2?
No — the C2 is speed-capped at 6 km/h which is a brisk walk. For running, the WalkingPad A1 Pro (max 6 km/h) or WalkingPad P1 (max 10 km/h) are alternatives, though we still do not recommend full-speed running on any folding treadmill this slim.
How loud is it during calls?
At walking speeds (2-4 km/h) it measures 48-52 dB at 1 metre — about the same as quiet office chatter. Video calls at these speeds are fine and colleagues cannot detect the sound.
Will it fit under a sit-stand desk?
Yes. The C2 is 12 cm tall when unfolded, so at an 110 cm standing desk height your typical walking stance clearance is about 98 cm — plenty for users up to 6’2″. For taller users or lower desks, verify clearance first.
Does it work with Apple Health and Fitbit?
Yes. The WalkingPad app syncs with Apple Health. Fitbit integration requires a manual data export. Strava is supported via the Health Connect integration.
What is the maximum user weight?
100 kg (220 lbs). For heavier users, look at the Sunny Health SF-T7515 or the WalkingPad R1 which supports up to 130 kg.
Do I need a mat underneath?
Recommended but not essential. A thin rubber mat reduces vibration transmission to wooden floors and protects carpet from belt-dust over time. Around £20-30 for a suitable mat.
