Shock absorption
Running smoothness
The equipment of a treadmill includes, among other things, motor output, size and quality of running surface.These provide a more comfortable motion and more safety for higher speeds respectively taller runners. A pc with many training programs offers more diversion while exercising. Extras like hot keys, folding mechanism, fan, and transport wheels make your workout much more comfortable.
Besides the frame construction, own weight and siize of standing surface guarantee a great stability. The more stable a treadmill is, the higher is the maximum weight load capacity and the more durable becomes the machine. Treadmills of high stability stand much safer for intensive training sessions. Furthermore, big rollers reduce wear and tear of the whole drive system.
Motor output, type of running mat, shock absorbers, and frame construction contribute to the running smoothness. An equipment of good running smoothness hardly causes any background noises and you can listen to music or watch tv while exercising.
Thickness of running mat and number as well as quality of shock absorbers are important for shock absorption features of a treadmill. A good absorption is joint-gentle and prevents early signs of tiredness.

Non-slip aluminium rails
The aluminium rails on the side of the running surface don't just look stylish, they also give the treadmill even more stability. They are also an additional safety feature, allowing you to simply jump off after or during your workout, without having to wait for the treadmill to slow down.

cardiostrong treadmill TR70i: get fit at home!

A large running surface, powerful motor and numerous clever programmes: the cardiostrong TR70i offers the best conditions for endurance training, losing weight and improving performance at home. The TR70 also provides entertainment: eight apps are already installed on the console for quick access. With Netflix, Twitter, YouTube, Chrome, Facebook, Bing, Amazon and Instagram, the treadmill training session goes by in a flash!

Advanced console with an outstanding variety of programmes

The cardiostrong treadmill TR70i offers 58 programmes – there is something for every training level and every training goal. Very simple to use: you can make all settings directly on the console touchscreen display. Use the direct selection buttons on the central console and handles to easily change the speed or incline even while running. In addition to the manual programme, which is activated simply by pressing the start button, the programmes are arranged in groups:

Heart rate programmes

With the training intensity controlled by the heart rate, certain training goals can be achieved more effectively. For this purpose, the cardiostrong treadmill TR70i has 2 programmes with 2 training modes each. Either your heart rate is kept constant by adjusting the speed or incline, or you can set the heart rate interval programme. Here, phases of higher strain alternate with phases of lower strain. The console sets the speed or incline so that you achieve the preset heart rate.

Virtual Route Videos

6 "Virtual Simulation" videos are pre-installed on the console. These are videos of running routes that you can watch on the screen during your training session. During the workout, you can change the speed or incline at any time using the arrow buttons or the quick selection buttons. The running videos react to your input. If you change the treadmill speed, the video playback speed will change accordingly.

Running Competitions

With these 12 competition programmes, you can compete against computer opponents on different terrains. These competitions make a nice change to your training session and give you extra motivation.

Profile Programmes

A total of 17 predefined profile programmes are available, which differ in terms of duration, intensities and changes in intensity. When selecting the programme, you can decide whether the intensity changes should take place by changing the incline or by changing the speed.

Custom running programmes

You can programme up to 20 user programmes yourself. The programmes consist of several sections and you can determine the desired incline and speed for each section yourself. Save the programme so that you can call it up again and again.

Manual mode – organise your workout to suit you

The simplest mode for the cardiostrong treadmill TR70i is the manual mode: just press Start in the main menu and off you go. But simple does not mean that you cannot add variety to the training session. You have full control over the training session at all times; all values are shown in an attractively way on the large display, and you can use the quick selection buttons to make quick changes to your settings.

Excellent engine performance and a very large running surface

The cardiostrong treadmill TR70i is equipped with a strong DC motor with 3 HP continuous output. This makes sure that the treadmill has an even acceleration and keeps the speed constant, even at high velocity. Even when you change the speed dramatically, the speed is adjusted linearly and very evenly. The treadmill offers you a top speed of 20 km/h. The generous running surface ensures you feel nice and secure, so you can give it all you've got.

Easy assembly, easy handling

The cardiostrong treadmill TR70i also offers all kinds of amenities before and after training. Following the instructions, the four-step assembly takes two people less than half an hour to complete. Thanks to a clever folding mechanism, you can fold up the running surface after training and simply use the castors to move the treadmill to wherever is more convenient.

Zeer fijne loopband, netflix, facebook alles erop
en by Alexander on 18.9.2016 4 Model: CST-TR70-2
It is really good, however after using for 1.5 months there are a few drawbacks: - The "speed -" button on right handle has a defect, but hopefully this fill be resolved as the appointment with repairman is scheduled. - The plastic motor cover creaks of metal parts when running (started after two weeks of usage). You... [Read more] have either to tighten screws every day to prevent this or have a makeshift laying between those parts. - The programming abilities are pretty limited. Basically whole run is divided into 20 equal parts and you set speed/inclination for every part. For example if your whole program is 30 minutes long, you cannot set 1-minute walk and 2-minute run, only multiples of 1.5 minutes. - Pre-defined programs are also pretty useless, and it's hard to guess what they actually do. So, only usable in manual mode. - The manual was for older model and in German. It would be nice if there were pdf versions of manual online, as apparently support has those (they sent manual in English to me upon request). - Phone application is really bad and buggy (but not really needed) - I wasn't able to make chest strap work, but even if I did it takes quite long to put on, so most people won't bother to use it anyway. - When the treadmill is stopped by pulling the emergency rope, it resets all settings rather then being simply paused. Quite annoying when you do that accidentally. - Buttons are a bit hard to press. - It has a EU plug even when ordered from Switzerland, so you have to change a wire! Also it is 13A device, so doesn't work with ordinary 10A Swiss power outlets. - As the treadmill is pretty light, tablet can jump off the tablet holder while running. :) Rubber band helps with that. Other then that, it's ok. :) I would surely buy it again. Works well, pretty robust. The motor is quiet. It's pretty light model, so you need to use thick mat for step vibration insulation. The display is very bright and easy to read. [Show less]

For the money, an excellent bit of kit
