How we test treadmills

We test treadmills from the most popular brands available at major UK retailers. Only we decide what we test – we don't have advertisers we need to keep happy, and no company can pressure us to test its products.

We also buy all the treadmills we test ourselves, and we regularly revisit the treadmills on sale to see if there are any popular, new models that need testing. When we find them, we do so. 

Running experience

• A panel of testers of various heights all run on the treadmills.
• The panel includes a range of skill levels, from casual joggers to marathon runners, so we can rate from a diverse set of experiences – not just a single person's opinion.
• They use the treadmills at various speeds and inclines to see how stable the treadmill feels, how comfortable it is to run on, how easy it is to increase and decrease speed, and how good the handrails are.
• Some treadmills are short, which is good for saving space, but can make it difficult for taller people to run on them.

Ease of use

• The panel rates each treadmill's controls and display, as well as how easy it is to get on and off the machine.
• We also rate how easy each treadmill is to build, factoring in the time taken for two people to assemble it and how easy the instructions are to follow.

Noise

• We rate each treadmill on noise, noting any irritating pitches and creaks. We also consider which machines are best at absorbing the sound of your footsteps.
• We measure how loud each treadmill is for both the runner and bystanders, at slow and maximum speeds.

Folding, storage and manoeuvrability

• We rate how easy it is to fold and unfold each treadmill, and whether the reduced size makes it easy to store.
• The best treadmills have clear grips and good wheels that make them easier to move around; the worst are like trying to move a mountain, or have so many fiddly steps to folding them away that you won't want to bother after a tough workout.

How to use a treadmill safely

• Keep children and pets away while in use Treadmills can have little gaps between the belt and frame, or space at the back where it's possible to touch the underside of the belt. If you have little ones in the house, keeping them out of the room while the treadmill is in use will reduce this risk.
• Remove the emergency stop (safety key) when not in use The belt can't move once the key is out. This will further help to keep children and pets safe.
• Clear the area around it The more space, the better – but you need at least 1.2 metres' clearance behind the treadmill. On either side of the equipment, we recommend leaving a space that's double the width of your treadmill. Never have the back of the running deck up against a wall or piece of furniture. If you lose your footing, you'll be sent backwards and may injure yourself.
• Always use the safety key If you fall, the machine will turn off and prevent further injuries.
• Start slow and work up This is so you can get used to the pace. You should also wait for the machine to come to a complete stop at the end of your workout before getting off.
• Make sure the treadmill is secure when folded away Some models fold flat and can be stored upright. Make sure it's properly secured and out of reach of little ones, so it can't be accidentally toppled.

How to lubricate a treadmill

Keeping your treadmill's belt maintained will help it last longer and potentially reduce wear and tear on other parts. 

It's important to check the instruction manual to learn how to tighten and lubricate the belt on your model. But as a general overview, here's how to keep the belt in top working order:

Tightening a treadmill belt

You should be able to lift the belt a few inches off the frame. If you can lift more than this, the belt is probably too loose. If you can't lift it at all, it's probably too tight.

1. You can tighten/loosen the belt on most treadmills by turning two heads (sometimes called adjuster holes) located at the back of the treadmill belt. You'll need a hex key to do this. Some manufacturers will supply the correct-sized key with the treadmill.
2. To tighten the belt, use the hex key to turn the head on each side of the treadmill clockwise. To loosen it, turn the heads anticlockwise.
3. Make sure you turn each head an equal amount.
4. Start with just a quarter to half turn of each head. This is so you don't overtighten or loosen the belt.
5. You shouldn't have to do many turns, so if after three full turns of each head the belt is still too loose or tight, contact the manufacturer for assistance.

Recentring a treadmill belt

Over time, the belt on your treadmill may slide left or right and no longer be centred. You'll be able to see this if the gap between the belt and the edge of the treadmill is much larger on one side than the other.

1. If the gap is bigger on the left-hand side of the treadmill, use the hex key to tighten the head on the left-hand side of the treadmill.
2. If the gap is bigger on the right-hand side of the treadmill, use the hex key to tighten the head on the right-hand side of the treadmill.
3. Start with a quarter to half turn, so you don't move the belt too much.
4. Switch on the treadmill and see if the space is now even. Repeat the steps if needed.

Lubricating a treadmill belt

You'll need to read your treadmill's instructions to see which type of lubricant to use. It's important to use the right one to avoid damaging the belt. For example, some treadmills use wax lubricant and need lubricating less frequently.

More commonly, though, belts use a silicone-based lubricant. You usually apply this by taking the following steps:

1. Unplug the treadmill.
2. Lift up the left-hand edge of the belt near the top of the treadmill.
3. Place the nozzle of the lubricant bottle between the underside of the belt and the base, roughly in the centre of the treadmill.
4. Pull the bottle back towards you, squeezing it to apply the lubricant as you do.
5. Repeat on the right-hand edge.
6. Turn on the treadmill and walk on it for a few minutes to help spread the lubricant around under the belt. 

Are treadmills good for weight loss?

Yes. Running or even regular walking has many benefits, including burning calories. Using a treadmill can be useful as part of a sustainable weight-loss plan.

You can run and walk outside, but having a treadmill in the home keeps you away from busy roads and poor weather. You can get even better results if you run on an inclined treadmill. They can also make it easier to squeeze a quick run into your busy daily routine.

Here are even more benefits you can get from a treadmill:

• Soft landing Many treadmills use a cushioned running deck to absorb the impact of your steps and protect your joints and feet.
• Smartphone connectivity Some treadmills let you plug in your phone or tablet to play music through built-in speakers. Some also work with fitness applications such as iFIT, giving you access to pre-set workouts for all fitness levels.
• Custom programs If you don't want to constantly tap speed and incline buttons, some treadmills have pre-set programs that change pace for you.
