Ironic illustrations are generally used to belittle hostile or backward things. They satirize with implicit tone to achieve negative publicity effect, while humorous illustrations are made by innuendo, allegory and pun.
Rhetorical device
In a well-meaning smile, expose those innocent and unreasonable things in life, so as to make people laugh and understand something from laughter; Humorous illustrations make advertising pictures interesting and make people accept advertising information in a relaxed situation.
Spinning posture map to avoid mistakes What is the spinning posture map? Correct riding posture can make you skinny and hip hop. However, some fitness friends always practice in the back row of the spinning classroom, always using the wrong riding posture, resulting in stronger thighs every day. Come and have a look at the spinning posture map, and put an end to the wrong riding way of spinning.

1. After the chair and the handle are adjusted to the correct height distance, put your hands in the center of the handle easily;
2. Imagine the feeling of walking in the park, and constantly use the three ways of "stepping, dragging and pulling" to draw a circle and trample;
3. Be careful not to open your feet. It is not recommended to stand on tiptoe when stepping on them to avoid cramps.
Special attention should be paid when pedaling spinning, and the knees should not be in the shape of an outer figure or an inner figure, so as to avoid unnecessary sports injuries and physical changes.

1. Sit your hips back and let your upper body lean forward slightly naturally. When you step on it and feel the power on your hips and thighs, you basically have the correct position of power.
2. Hold the handle slightly away from the sitting position, step on it and pay attention not to twist the upper body too much, so that you can exercise the lower body correctly.
When doing this position, you can imagine that the flywheel of the spinning bike is taken away and you are running on the treadmill. In addition, avoid the upper body being too straight.

1. You only need to hold the handle at the top of the spinning bike for standing and running.
2. You can use the strength of the abdominal muscles to trample, but you should still pay attention to the hip sitting back, and the upper body naturally presses forward slightly.
3. Raise the resistance and imagine a ride to the top of the mountain.
Schematic diagram of riding posture Avoid supporting your arms on the handlebars.
Spinning trainers should always remind themselves to hold the handlebars easily and focus on the pedals instead of supporting them with their arms.
The error demonstration is as follows:
Rotating cycling posture shows that the knee elbow can't be buckled inside.
During the rotation, the elbow buckle shows that you are overexerting. The correct state should be that the elbow is naturally relaxed and presents a natural physiological bend.
In addition, riding a spinning bike with a knee buckle can cause knee injury, pain and body deformation. Pay special attention to the knee movements when riding, and let yourself develop good habits.
Don't support your arm and wrist at this opposite angle, which will cause the weight of your body to press on your wrist, and in severe cases, it will hurt your wrist.
Rotating riding posture illustration Sitting posture can't hold the highest position when riding.
This posture is wrong (as shown in the figure), which leads to the thigh backward in the extreme position of pedaling and stretching, and the muscle tension of the buttocks cannot be maintained. Moreover, this riding posture deepens the stimulation of the muscles in the front of the thigh and cannot exercise the buttocks.

How to ride a spinning bike is the correct posture? Riding a spinning bike is just like riding a bike. In order to avoid sports injury, the exercise mode must conform to sports physiology.
When buying a bicycle, specialty store will make a basic fitting for the customer. What determines this pipe fitting is mainly the size specifications of the valve body "riser (including seat pipe)" and "upper pipe (including faucet)"; When the store recommends cars to consumers, it determines which cars are suitable and which cars are not suitable according to the customer's body shape (the length specifications of the riser and the upper pipe).
Back to the theme of rotation. Professional spinning bikes generally have the functions of stepless adjustment of seat back and forth/height and stepless adjustment of handle back and forth/height. Spinning seat can adjust its height back and forth, which is basically equivalent to a lifter with variable length and angle. The handle of the spinning bike can be adjusted back and forth, which means that the length of the upper pipe and faucet can be adjusted. Therefore, the function of professional spinning bike is basically the same as that of FittingBike, but even such a spinning bike that can be fitted should not be adjusted after consumers buy it back. Improper wearing can easily cause sports injuries. Let's talk about the basic adjustment of spinning bike:
First, the size of the elevator-adjust the height of the seat
The lifter is the main structure supporting the seat cushion. In sports physiology, the length of the riser is actually related to the length of the arm when riding, that is, the leg length of two legs. Imagine that your thighs and calves are arms with a fulcrum (knee) in the middle, and you step on a circular trajectory. The longer the arm, the higher the efficiency. On the other hand, the shorter the moving arm, the more power the fulcrum of the moving arm (that is, the knee) consumes, which also leads to the increase of knee pressure. Generally speaking, novices who have never ridden a spinning bike will always feel more comfortable with a lower seat, but temporary comfort does not mean sports safety. Let's look at the picture and tell a story:
Correct seat height position: the arm of force is long and the legs are spread apart, so that the force can be released.
Seat height is too low: the arm of force is short, and the force accumulates at the corner, which not only makes it difficult to contribute, but also causes sports injuries.
Simple fitting can calculate the "span length" by formula, and multiply the result by a fixed number (such as 0.87, 0.88, etc.). ) Get the straight line distance from the seat cushion to the center of Wutong Bridge. In fact, leg length is not the only parameter that determines the distance from the seat cushion to Wutong Bridge. For example, whether the hips are involved in the trampling action and whether the ankles are pressed down are simple examples of personal exercise habits and actions affecting the arm length.
Second, the angle of the lifter-adjust the seat back and forth.
The angle of the lifter determines the center of gravity of the body when riding. The greater the angle of the riser, the more forward the center of gravity during exercise, and the greater the explosive force of trampling; The smaller the riser angle, the more backward the center of gravity moves during exercise, the more relaxed the upper body is, and the easier it is to ride for a long time. As far as bicycles are concerned, the riser angle determines the competitiveness or comfort of the car. However, as far as spinning bike is concerned, because the riser angle can be changed in disguise through the front and rear positions of the seat cushion, the image setting of the bicycle is not mentioned here, and the included angle between thighs and calves during exercise is further discussed in exercise physiology. Generally speaking, novices who have never ridden a spinning bike always feel that their upper body is a little relaxed and will try to adjust their seats forward, but such comfort will also have security concerns. Let's look at the picture and tell a story:
Correct sitting posture: when pedaling, the included angle of knee joint should be large to avoid pressure on knee and ankle.
The position before and after sitting is too forward: the included angle of knee joint becomes smaller when pedaling, and all the strength is accumulated at the knee joint, which is easy to cause sports injury.
Simple fitting requires that when the foot moves to the horizontal position, the front pedal shaft, thumb ball and knee joint present a vertical line perpendicular to the ground. In fact, everyone is different, and the length ratio of thighs and calves is also different. To reach the three-point * * * line, the front and rear position of the seat must be properly adjusted. For example, the thighs are long and the seats need to be adjusted later; If the calf is long, the seat needs to be adjusted forward.
If the seat cushion is positioned too far forward, it will cause excessive pressure near the knee. Excessive use of quadriceps femoris will cause muscle strain and damage the soft tissue of knee joint and iliotibial tract. The position of the cushion is too big for the queen mother, which will cause great pressure on the ankle joint and the problem of muscle overuse.
