Duke 500, or Duke 550, if it is a physical store, it must be more expensive than Merida in the same level of Giant, because the Giant brand is larger, so he costs more, and your 17 or 16-inch frame is about the same.

1. Ordinary bicycles are not the same as sports bicycles. There are two options for people who want to achieve fitness by cycling, mountain biking and road biking. The former is slow, but can adapt to complex terrain and is suitable for riding and fitness in the wild; The latter is suitable for the fitness requirements of the pursuit of speed, and has a good exercise effect on people's muscles, cardiopulmonary function.

Second, experts remind fitness enthusiasts that compared with other sports, cycling has higher requirements for the safety protection of cyclists themselves.

1. First of all, it is necessary to be equipped with professional protective equipment, such as helmets, gloves and shoes. Helmets play an important role in protecting the head during high-speed riding.

2. Pay attention not to expose your forehead when wearing it;

3. Gloves can prevent slipping and abrasion;

4. Sponge-soled sneakers, the soles of the feet will swell after pedaling for a long time, while professional bicycle shoes have hard soles, which can make the pedaling power all concentrated on the pedals.

I live in an old neighborhood that is a teacher's apartment next to the school, and there are only three buildings in the whole neighborhood, and there is a very long and spacious carport downstairs.

The first car I put there was my girl's children's car, with a bright red frame, dark wheels, a gorgeous appearance, and a small flower umbrella with lace hanging on the handlebarsBecause of its small size, it is placed there, just like its owner, and has an arrogant and cute energy.

Since she was 3 years old, the girl has been riding it all over the stairs of her father's unit. Like a doll, she is a girl like the wind. With a fiery red Sun Tan defeated, he drew a smooth arc in the open area of the community.

That summer, she was about 150 centimeters tall, and when the new gearcar came into her life, the little red car waited in the carport, covered with thick dust, and no longer saw the dazzling appearance of the year, it just lay there silently waiting for the end of its life cycle.

When the girl was 7 years old, her father said that he had spent 40 yuan on a second-hand bicycle. Said that the unit was too close and it was a waste of time to park by car.

After that, I don't know if he rides a bicycle to work, but the girl no longer wants me to drive her to dance class, and she trembles, saying that it is only good if her father sends her, so that she can be happy on the road. There is wind, there is sunshine, sometimes there is rain...

More than ten years have passed like a shuttle, fleeting, and the time with the child felt so long at the time, and now it feels so short! Her growth will not wait for me, and suddenly I find that she has gone away, and at the same time I am relieved that she has her own world.

Cycling fitness includes aerobic cycling, strength cycling, strength cycling, interval cycling, and foot cycling. When exercisers do aerobic exercise on a stationary bike, during the first 20 to 30 minutes of exercise, they consume glycogen converted from food in the body. After 30 minutes of exercise, the body begins to break down the fat in the body.

Less than 40 minutes of stationary bicycle exercise, although it can have a certain effect on the heart and lungs, but it does not burn more fat. If you pedal a stationary bike for more than 1 hour, your body will metabolize more of your muscles, not the fat that the shaper wants to lose. However, the more muscles in the human body, the more calories are metabolized, so that it is not easy to gain weight.

1. Aerobic riding: riding at a medium speed, generally riding continuously for about 30 minutes, and at the same time paying attention to deepening breathing, which is very beneficial to the improvement of cardiopulmonary function, and also has special effects.

2. Intensity riding: first of all, it is necessary to stipulate the speed of each ride, and secondly, to stipulate the strength of your own pulse to control the riding speed, which can effectively exercise the cardiovascular system of the person.

3. Power riding: that is, to ride hard according to different conditions, such as uphill and downhill, which can effectively improve the strength or endurance quality of the legs, and can also effectively prevent the occurrence of thigh bone diseases.

4. Intermittent riding: When riding, first ride slowly for a few minutes, then ride fast for a few minutes, then slowly, then fast, so that alternate cycle exercise, can effectively exercise people's heart function.

5. Foot riding: Cycling with the sole of the foot touching the bicycle pedal can play a role in massaging acupuncture points. Here's how:

When pedaling with one foot, the other foot is not forced, and the bicycle is driven forward with one foot, 30 to 50 times at a time, and the effect is better when the wind or uphill is exercised.

Best results: There are many kinds of healthy, fat-losing exercises, and a pedaling bike with a bad bench in the gym is a good choice. But pay attention to the amount of time you exercise, not too little and not too much.

In the gym, stationary bikes are the most popular, because not only can you sit on them to watch TV and listen to ** when exercising, but even the recumbent stationary bike is equipped with a backrest, which is really comfortable.

For beginners in cycling, it is recommended to pedal lightly in a small or medium plate when practicing the car, and let the heartbeat (maintain a speed of at least 25 or so per hour), so that it is necessary to practice cardiopulmonary function, similar to aerobic exercise, after enhancing cardiopulmonary function first, about half a year, and then practice ** pedaling, that is, muscle strength training, so that whether it is a flat road or a hill climb has a great help.

PS: Suitable for both mountain bikes and road bikes.

First of all, the bicycle is two wheels, the balance must be mastered, there is a possibility of falling down, and beginners will inevitably have blue nose and swollen eyes; Secondly, as an exercise, it may be necessary to be physically better; Finally, it is recommended to consult the bicycle transportation center for details. There is no need for a driver's license, and the license plate has been hung up when ZF has cramps before, and it is estimated that it has little effect, and the bicycle has rarely been detained because of the license plate problem; The drunk driving limit is not as strict as that of a car, but it is recommended that it is best not to drink and drive, as it is the most dangerous for yourself.
