Treadmill Terminology Explained

The moving part of the treadmill which you run on. Also known as a running deck. Its always best to buy a treadmill with the largest belt or running deck that you can fit in your home. This will allow you plenty of room to sprint without space restriction.

Measured in kilograms, this is the total treadmill weight. Heavier machines generally have a better build quality and are more stable when you run.

There are two types of heart rate monitor; hand sensor monitors and wearable monitors. Hand sensors come with most fitness machines and take your pulse through the hand grips, they are good as a guide but rarely very accurate. Wearable monitors such as chest straps and watches are generally much more accurate than hand sensors.

Target heart rate training can be used to assist goals ranging from fat burning and weight loss to maximum aerobic capacity development. A target heart rate zone is selected before working out based on the users individual goal. A strap or watch will then monitor your heart rate, giving you real time feedback so you can maintain the right level of effort to stay in your selected target zone. Many fitness machines link to chest straps or watches and auto adjust resistance levels to help keep you in your target zone so it is worth checking product detail pages if you are interested in this type of training.

The tilt of the running deck that simulates uphill running.

The term ‘horsepower’ is a unit of measurement for motor size. A large horsepower (3hp or more) generally indicates a higher quality motor which will last longer than a small motor size. Retailers often list two ways of measuring the horsepower, continuous and peak. For example, 1.75 horsepower, 3 horsepower peak. We suggest you focus your attention on the continuous duty rating, which is the lower of the two numbers.

Some lower quality treadmills refer to their power in watts. There are 750 watts to 1 horsepower unit. If you are hoping to run over 3 times per week, or you weigh over 10 stones, we suggest that you look for a treadmill with a 1.5 horsepower motor or more.

Range and variety of pre-programmed workouts available on a motorised treadmill.

Customer Reviews

"JTX 9 best treadmill and JTX Fitness best company"

"Mrs Loren Castaldi" - 22 Jul 2016

I love my JTX9 and here is why: I have tried several treadmill, from the magnetic ones to the cheap motorized ones. Non of them worked for me. I always ended up with pain in my legs and lower-back, so I was a bit skeptical of buying this product. Before buying it I had asked loads of questions to the customer support team and I always got professional and reliable answers and not even once I was pushed to buy the product. The professionalism and the customer service received, together with the option of being able to return the product if was not of my liking made me come to the decision of buying it. I have to say I do not regret it at all. It's a great machine, that has nothing to envy to the commercial ones. I am not a runner, actually I have not being able to run for the past 2 years due to a surgery to remove cancer from my knee and part of my quadriceps. Once my knee was able to support my weight again while "running", I have started jogging outside, but I fund it difficult due to the fact that running on tarmac is hard plus you have natural inclination of the road. With JTX 9 I am actually able to run for over 20 minutes with no discomfort whatsoever. I would recommend this fantastic product to everyone looking for a good machine and the fact that this company provides a customer service second to none is just a great added plus to make your buy easier, more enjoyable and absolutely more reliable.

"Sprint 9 - Superb!!!"

"FRASER MCCALLUM" - 18 Jul 2016

Absolutely delighted with the quality of this machine and the excellent customer service provided by this fantastic company! As a relatively quick runner I was after something that still felt solid and reliable at quicker speeds. 17 and 18 kph. This feels as smooth at 18kph as it does at 10 kph and is also very quiet. It feels and looks like a gym spec model. Looking forward to a winter of speed and hillwork before a sub 3 marathon attempt in the spring. Would recommned company to all family and friends. Fraser M

"Terrific Treadmill"

"Hilly Kendrick" - 18 Jul 2016

Purchased the JTX 9 Sprint Treadmill last October and not looked back.Easy to set up and good helpful guys to answer questions. Brilliant heavy duty machine just as good as the one I used at the local gym -before it closed! NOW I have my own little gym here at home.Use it Monday -Friday, it has become my life saver! Losing weight and getting fit AND enjoying myself! Thank you JTX!

"Good company, good treamill and exceptional price"

"Jon" - 18 Jul 2016

Actually I had not heard of JTX Fitness until recently but they have impressed me with their treadmill and their great customer service. The sales people did not sound like sales people and they gave me some very good advice. Their initial advice was that I should run outside while it is sunny. Actually I need a treadmill because I need to run on a constant incline. I have bought the sprint9 treadmill and it looks and feels like the one in the gym. I'm pleased with the price and I've spoken with JTX a few times since purchase. They've helped me to get it set up properly and also given me a basic training programme. I'd recommend this company and their product appears to be very good so far.

"Superb quality treadmill at a great price"

"MikeW" - 18 Jul 2016

Having bought a excercise bike from JTx before I knew I was dealing with a good company and was happy to return to them when we wanted more kit. I got into fitness late last year on doctors recommendation and its turned my health around. I can now run 6 KM non stop and feel so much better. We ve now set up our own gym in the garage. The most important piece of kit to me is the running machine. I didnt want a flimsy treadmill that would break within a year. I wanted a heavy duty gym one with a heart strap that can take heavy use from me and the family. I use the heart rate programme H1 to run at 50-70% of my MHR, careful to not overdo it. Strong, quiet ,solid and sturdy build the sprint9 is a very good product and i can happily recommend it to anyone wanting a high quality treadmill for a good price.
