Max. user weight

The highest weight of an athlete, at which the treadmill can work indefinitely for a long time (at least during the warranty period) without negative consequences. Most modern models have a "weight category" of the order of 150 kg and even more, which allows them to be used even by people of large build. However, there are exceptions, so this parameter is still worth paying attention to when choosing a treadmill.

It is worth choosing a model by weight with a significant margin — at least 10 kg more than your weight, even if you expect to lose it during training. If, on the contrary, you are going through a comprehensive training course to gain weight, then you should focus on the result you want by the end of the course. Anyway, the "weight category" of the machine must be greater than the weight of the user. Otherwise, the device will work with off-design loads and may break at any time.

If the treadmill is planned to be used for several users, you need to focus on the weight of the heaviest of them.

Min. running speed

The slowest speed at which the treadmill belt can move. This parameter is indicated only for electric models (see "Load system"), as in other types, it depends solely on the user himself.

The ability to operate the belt at a low speed is important if strong loads are contraindicated — for example, during the rehabilitation period after injuries. In many modern models, this figure is only 1 km/h (even though the average walking speed of a healthy person is about 5 km/h). Thus, they can be used even with serious injuries, when normal walking is very difficult.

Max. running speed

The highest speed at which the treadmill belt can move. This parameter is indicated only for models of the electric type (see above). For mechanical and magnetic ones, it depends solely on the capabilities of the athlete himself, and it is impossible to accurately indicate the maximum speed in the characteristics of such machines.

The higher the maximum speed the greater the load can be given to the athlete and the better the treadmill is suitable for intensive training. However, for home models, a speed of 15 – 16 km/h is considered quite sufficient; "faster" machines usually belong to the advanced class and are designed for professional athletes.

Note, that for everyday use it does not always make sense to chase a high maximum speed. If your level of physical fitness is not high or if high loads are undesirable, a speed of 10 – 12 km/h may well be enough.

Motor power

Power of the motor installed in the electric treadmill (see "Load system"). This parameter is directly related, first of all, to the smoothness of the belt movement and the maximum speed (see above) — the more powerful the motor, the more uniform the movement of the belt will be and the faster it can move. Also, motor power determines the resistance to high loads: with an equal weight category (see "User weight"), a more powerful model is better suited for people with large body weight, especially at high speeds.

In general, most recreational treadmills have motors between 1.5 and 2.5 hp; more powerful options usually belong to the professional class.

It is worth noting that above we were talking about the constant power of the motor — that is, the power with which it can work for a long time without being subjected to overloads. In some models of treadmills, the so-called peak power — the power that the motor can develop for a short time, for a few seconds. It is higher, but long-term operation at such a load is fraught with the failure of the device. Therefore, before buying, it is worthwhile to clarify, if possible, what power is implied in the specs — nominal or peak; this is especially true for high-power models.

Running belt size (LxW)

Under the dimensions of the belt in the specs of treadmills, they usually mean the dimensions of the working area — that is, the running deck within which the user's feet stay during training. Several points determine the optimal length and width of the belt.

The long treadmill length ensures safety — less likely to seriously stumble and fall out of rhythm. On the other hand, a long belt requires a more powerful motor, and the dimensions of the treadmills increase accordingly. With all this in mind, it is believed that the optimal length for home use is 120 – 130 cm; longer belts are designed for use in fitness centres and professional training.

Both safety and comfort when using the treadmill also depend on the width of the belt. This parameter is especially important for people of large build — on a narrow canvas, they can be “cramped”. On the other hand, as in the case of length, a large width means a large size of the treadmill itself. In general, entry-level models have a belt up to 40 cm, in more advanced treadmills there are options for 45 cm, and for professional use, this figure can reach 50 cm.

When choosing a treadmill according to the size of the belt, it is best not only to take into account all of the above, but also to try out the option that interests you before making a purchase. After all, a lot depends on personal characteristics and preferences, and a seemingly suitable treadmill may be small — or vice versa, a more...compact and inexpensive option is quite suitable.

Dimensions

The dimensions of the treadmill in the assembled state. It is important to note that more space is needed for the comfortable and proper operation of the treadmill.

Weight

The total weight of the treadmill when assembled.

All such treadmills are quite massive — models weighing up to 50 kg are considered light. And when choosing, it is worth considering that both small and significant weight have their advantages. So, lightweight designs are more convenient when moving, while weighty ones are more stable, often have more extensive functionality, and are also better suited for people with large body weight.
