The fitness equipment range in the sport and outdoors department includes full-size treadmills and compact walking pads. Both let you walk or run indoors, but they differ in motor strength, belt size, noise and storage. This guide explains the specifications you will meet, how to match them to how you plan to exercise, and what to measure at home before buying. General exercise information only: if you have a medical condition or have not exercised for a long time, ask a doctor before starting a new routine.
Walking pad or treadmill
A walking pad is a low, slim belt with a modest motor, designed mostly for walking at speeds up to about 6 km/h, sometimes higher. Many fold flat or have no handrail, so they can slide under a sofa or bed. They suit desk walking and light daily activity. A conventional treadmill has a taller frame, handrails, a larger belt and a stronger motor, and is meant for sustained jogging or running as well as walking. If your plan includes running, a walking pad is usually not designed for it, and the manual will state the maximum speed and use.
Motor power
Motor power is stated in horsepower (HP) or watts, and there are two figures to know. Peak power is the highest the motor can reach briefly. Continuous power (CHP) is what it can maintain. The continuous figure is the better indicator. Walking is generally comfortable with about 1.5 to 2.0 CHP, jogging with around 2.0 to 2.5 CHP, and regular running with 2.5 CHP or more. A heavier user needs a stronger motor to maintain smooth operation. If only peak power is given, treat it with caution.
Belt size
The running surface is given in centimetres, width by length. For walking, a belt around 40 cm wide and 100 to 120 cm long can be adequate. Jogging is more comfortable with a width of about 42 to 45 cm and length of at least 120 cm. Taller users and runners with a long stride need a length of 130 to 150 cm. A short belt makes you shorten your stride, and a narrow one reduces the margin for movement.
Speed, incline and programmes
- Speed range: shown in km/h. Typical walking pads cover 1 to 6 km/h, treadmills 1 to 12 or up to 20 km/h.
- Incline: manual incline is set by hand, motorised incline by remote or console. An incline of 10 to 15 percent adds intensity without a higher speed.
- Preset programmes: interval and hill programmes help structure sessions. Check that you can also set a manual speed.
- Heart rate sensors: handlebar contact sensors are less accurate than a chest strap or watch. Check for Bluetooth to pair a separate sensor.
- Console data: time, distance, speed and estimated calories. Calorie figures are rough estimates.
Maximum user weight
Every treadmill has a stated maximum user weight in kilograms, commonly 100 to 150 kg, and walking pads often 100 to 120 kg. Choose a model with some margin above your weight, because this affects both safety and durability. Do not exceed the limit stated in the manual.
Cushioning and noise
Deck cushioning absorbs impact and reduces strain on joints. Models with multi-layer belts and elastic dampers feel softer than those with a rigid deck. Noise depends on the motor, belt and floor. If you live in a flat or exercise early or late, check the noise description and consider a mat to reduce vibration. A walking pad is quieter in general, which is part of why it is used at a desk.
Folding and storage
If space is limited, a foldable frame matters. Check the folded dimensions and weight, whether a gas strut assists lifting, and whether wheels allow you to move it. Measure the doorway and the storage location, not only the exercise area. Behind the machine, keep a safe clearance recommended by the manual so that you can step off safely if you stumble, and in front leave room for the console and handrails.
Assembly, power and safety features
Most treadmills ship partly assembled and need a few bolts and a connection to the console. Check the power requirement; most use a standard household socket. A safety key on a lanyard stops the belt if you move away, and it should be attached to your clothing whenever you use the machine. Lubrication of the belt is part of maintenance; some belts are pre-lubricated and others need silicone lubricant at intervals given in the manual.
Pre-purchase checklist
- Decide whether you will walk, jog or run, and choose the machine type accordingly.
- Check continuous motor power rather than peak power.
- Match belt width and length to your stride and height.
- Confirm the maximum user weight has a margin.
- Choose incline and speed ranges that fit your plans.
- Measure the exercise area, the folded dimensions and the route to storage.
- Check the safety key, and the noise level for your living situation.
- Ask a doctor if you have health concerns before starting.
