According to the merchants selling fitness equipment in Jinan, there are nearly 100 kinds of fitness equipment on the market at present. Treadmill, rowing boat, exercise bike and spacewalker are four kinds of home fitness equipment preferred by citizens: Treadmill: Treadmill, also known as walking machine, walking machine or flat treadmill, has two kinds of single-function treadmill and multi-function treadmill, and is the "darling" of indoor fitness equipment. Running is an internationally popular aerobic exercise, which is highly praised by the medical and sports circles. It is the most effective and scientific method to maintain physical and mental health, and it is more and more loved by everyone. However, due to the limitation of urban environment, many people can't enjoy down-to-earth and close to nature running, so the treadmill has become the first choice for bodybuilders, especially women who want to lose weight quickly. During exercise, the electronic watch on the treadmill can help you write down the speed, time, heart rate, calories, beat, distance and other indicators, so that athletes can master their physical condition at any time and make adjustments. If the physique is poor, it is appropriate to take 100 ~ 200 calories at first, and it can be increased to 200 ~ 300 calories after the physique is gradually improved; People with moderate physique can consume 200 ~ 400 kilocalories each time; Those with good physical fitness can consume more than 400 kilocalories (the specific situation varies from person to person). Walking or running on a treadmill is almost the same as walking or running on the ground in peacetime. But judging from the actual strength of the human body, it saves stepping and stretching actions than walking or running on land. It is this that makes bodybuilders feel very relaxed and comfortable, running 1/3 more distance than on land and consuming more energy than training on land. Treadmill is suitable for people who want to lose weight (male or female), especially for women who want to lose weight quickly. The reference price is about 2500 yuan to 5000 yuan, or more than 10 thousand yuan. Rower: Take care of the muscles that can't move on weekdays. When rowing, about 90% of extensors participate in sports, so it is really good for extensors who rarely participate in any movements. Rowing has an obvious effect on training back muscles, which can make the back get the maximum range of motion when the body flexes and stretches, and at the same time effectively move all joints of the spine, which not only enhances elasticity, but also increases toughness. When practicing "rowing", we should pay attention to the consistency of movements, and there should be no pause every time we push and stretch. The movements in rowing must be in place. If the amplitude is too small, the muscles involved in the exercise cannot fully stretch or contract. The rowing machine is suitable for people who are inactive on weekdays, especially for middle-aged and elderly people. Exercise bike: the reference price of bicycle is 2000 -2800 yuan and above. The exercise bike has incomparable advantages over bicycles-you can freely play your riding speed, and you can observe the speed, time and heart rate of every moment through the electronic watch on the exercise bike. Exercise with it can not only effectively improve cardiopulmonary function, but also help to strengthen leg muscles, lose weight and improve physical fitness in an all-round way, especially for patients with mobility difficulties, weak constitution and need rehabilitation. There are two kinds of exercise bikes: one is fixed handle, which is only suitable for pedaling; The other is a movable handle, which takes into account arm and leg training. There is also a backrest-type exercise bike, whose backrest-type body design can effectively exercise thigh muscles and increase the comfort during exercise. The armrest exercise bar attached to the machine can not only balance the exerciser's body, but also enhance the muscle strength of both arms. With the development of science and technology, the exercise bike has been computerized, and the screen on the handlebar will display various data, such as heart rate, breathing frequency, time, speed, distance, energy consumption and so on. These data are convenient for exercisers to master the amount of exercise and adjust the intensity of exercise in time. In some cars, different landscape pictures can be displayed on the color screen, which makes the exerciser feel relaxed and not bored, just like on the road or in the field. Riding an exercise bike requires almost no technology, but the purpose of exercise is different, and the riding methods are different. There are mainly the following types: aerobic exercise riding method, which can achieve the purposes of fitness, auxiliary medical care, preventing obesity or losing weight, and improving cardiovascular function.

The reference price ranges from 2000 yuan to nearly 10 thousand yuan. Elliptical machine, also known as spacewalker, is a new type of fitness equipment.
