Leg sister fitness for 10 years, 7 years of practice, contact with a dozen or twenty gym treadmill, but also to help many stores to purchase a treadmill, the used treadmill is much more than talked about the boyfriend.
Therefore, according to the leg sister’s many years of experience, the treadmill purchase method is summarized as a simple “3 views”, these three points are the real core points, and the others can be put back.
1, how to judge the performance of a treadmill?
The motor is the core of a treadmill, just like the engine of a car, so the quality of the motor directly determines the performance of a treadmill.
There are two parameters that reflect the performance of the motor: continuous horsepower (CHP) and peak horsepower (HP).
Peak horsepower
Peak horsepower indicates the maximum driving force that the treadmill can achieve instantly, in order to make the treadmill respond to sprint or maximum load for a short time, but this power cannot be sustained, otherwise the light will dry stop, and the heavy will dry smoke.
It’s like a sprinter running 100 meters in 10 seconds, but he can’t run a marathon in 100 meters.
Therefore, the peak horsepower does not have much practical significance, do not need to pay attention to, and because this value looks larger, it is often used by businesses to deliberately promote consumers.
Sustained horsepower
Sustained horsepower, also known as rated power, indicates the driving force that the treadmill can steadily output for a long time, and only the sustained horsepower is large enough to allow you to run how you want to run.
Usually 1CHP can provide about 50~60kg of carrying weight, if the sustained horsepower is too small, the weight is too large, the running process may occur stall or stop.
There is no doubt that the greater the sustained horsepower, the better, but the greater the sustained horsepower, the more expensive the price must be. For those who want to pursue cost-effective students, leg sister suggests combining the weight of family members and following the principles in the above brain chart:
(1) Continuous horsepower 1CHP and below belong to the category of walking machine, see it directly PASS, 1.25CHP is the pass line.
(2) Sustained horsepower 1.25~1.5CHP is an entry-level treadmill, the price is usually below 3k, and people below 75kg can use it.
(3) The treadmill with a sustained horsepower of 1.5~2CHP is the most cost-effective, the price is generally about 3-4K, and the population below 100kg can be used, basically meeting all family needs.
(4) Sustained horsepower above 2CHP belongs to the high-end treadmill, the price is more expensive, suitable for large weight, or need sprint training crowd choice, but more than 100kg large weight, leg sister is often not recommended to use the treadmill.
2, treadmill shock absorption system which is good?
If the treadmill is compared to a car, the motor is the engine, and the shock absorption is the suspension system of the car.
Treadmill compared with outdoor running, an obvious advantage is its own shock absorption, good shock absorption effect can greatly reduce the running on the ankle joint, knee joint damage, can also appropriately reduce the running noise on the downstairs neighbor interference.
Do not be confused by various seemingly high-end nouns in business advertisements, what aviation shock absorption, what maglev shock absorption, and even a bunch of English words, in the final analysis, is the following solutions.
No shock absorption/running belt shock absorption
Most of the one or two thousand treadmills have no shock absorption system, and some products may introduce how many layers of running belts are used, which is not a real shock absorption system, and this type of treadmill leg sister is not recommended.
Spring damping
Spring shock absorption is installed between the bottom frame and the running table support frame to cushion the vibration brought by running, and does not directly react to the knee, so the degree of protection for the knee is general.
And spring shock absorption is difficult to find a balance point to adapt to all the weight of the population, long-term high-strength use, the spring will have elastic loss, the damping effect is reduced, and the later maintenance cost is high.
Rubber/silicone shock absorption
Rubber shock absorption is to install a plurality of rubber columns or rubber pads under both sides of the running plate, with the elasticity and cushioning of rubber, absorb the impact of running, and the more rubber is used, the better the shock absorption effect.
Rubber shock absorption technology is not difficult, is currently the most widely used, the most cost-effective solution, the characteristics are better to distinguish, if you see the running board under the similar strip, columnar material, no matter what the name of the business, all are rubber shock absorption solutions.
The disadvantage of rubber shock absorption is that it can provide limited elastic buffer for large weight groups. Airbag shock absorption
Air bag shock absorption is also installed under the running plate, the use of air cushion or air bag to absorb the impact generated during running, and the more air cushion used, the better the shock absorption effect.
The air cushion can automatically adjust the hardness according to the weight of the runner and the intensity of running, so the applicable population is relatively wider, the disadvantage is that the price is more expensive, only a few brands such as Reebok have patented technology.
3. How wide is the running belt appropriate?
The area of the running belt is related to the comfort and safety of our running.
The average shoulder width of adult men is about 41-43cm, the average shoulder width of women is about 30-40cm, in order to adapt more people, we require that the width of the running belt must be greater than 42cm, so that runners can freely swing their arms to run.
At the same time, considering that the stride length of the runner is at least 0.6 times the height, in order to ensure that the leg can be stepped when running, and there is a margin before and after the landing point, we require that the length of the running belt must be greater than 120cm.
(1) Width 43cm-48cm, length 120cm-132cm: it is the running belt size of the entry-level treadmill, and it is also the minimum that adults can tolerate, meeting the walking, climbing and jogging needs of people below 170cm height.
(2) Width 48cm-51cm, length 132cm-141cm: it is the most cost-effective choice, not only the price is moderate, but also suitable for a wide population, height below 185cm can be used.
(3) More than 51cm wide and more than 144cm long: families with sufficient budget and sufficient family space can elect as many elections as possible.
Note: the width of the running belt refers only to the width of the conveyor belt, not including the non-slip edge strip on both sides, we should pay attention to the size and illustration of the business when choosing, do not be fooled by the business of playing careful machine.
4. What other performance parameters of the treadmill are worth paying attention to?
4.1. Slope adjustment
Leg sister here to teach you a little trick, in fact, the best way to open the treadmill is not running, but climbing, the appropriate slope can not only improve the efficiency of burning fat, but also reduce the pressure on the knee.
Because climbing requires overcoming more gravity to do work, so the fat burning efficiency is higher, this need not be explained.
Second, studies have shown that:
(1) Medium slope (2°~5°) : it is the most friendly to the knee, and the pressure on the knee under this slope is the least, which can meet the knee pad and efficient fat burning at the same time.
(2) High slope (5°~8°) : Although the fat burning efficiency is further improved, the knee pressure will also increase relative to the moderate slope.
(3) Low slope (0°~2°) and downhill (-9°~0°) : not only does not reduce knee pressure, but also increases knee and ankle pressure, while downhill also reduces fat burning efficiency.
4.2. Net weight
The greater the net weight of the treadmill, the more solid the material used in the whole machine and the better the stability.
4.3. Maximum load bearing
The load-bearing labeled by the merchant, such as 120kg, does not mean that the treadmill can be used below 120kg, this load-bearing refers to the load-bearing upper limit of the treadmill running board, beyond this upper limit, the running board may be broken, so it is recommended to look at the maximum weight of sustained horsepower support.
4.4 Whether it can be folded
For families with limited space at home and storage needs, they can pay attention.
4.5. Control Panel
The most practical is the LED/LCD screen + mechanical buttons or shuttle knob control, because the simpler these functions are, the more cost the business will spend on the core components and design, those fancy big screen is not necessary.
Remember, you need a treadmill, not a nice clothes rack and storage rack!
