2、Training Guide
The correct use of the exercise bike can make the buttocks and legs more healthy,
increase the oxygen in the blood volume, and make the spirit more relaxed. So how can we
use the right bike safely?
First: warm up in front of the exercise bike
Full warm-up exercise before exercise is indispensable, such as jogging, squatting, high legs,
leg pressing, pronunciation, waist twisting, arm movement. And so on the activity, causes the
body micro perspiration hot, generally in 5-10 minutes.
Second: adjust the height of the exercise bike seat and the front and back position and
handle height
To make the most of your exercise and ride as efficiently as possible, make sure your seat is
properly adjusted. It will also make you more comfortable.
1. Seat height adjustment: sit on the seat and put your foot on the pedal so that the toe ball is
above the pedal axis. When the pedal is at the lowest point, you should see the knee bend
slightly at an angle of 25-30 degrees. The pedal force in this position is maximum and most
comfortable. If the hips swing back and forth on the seat, the seat may be too high. In this
case, please lower the seat.
2. seat adjustment: sitting on the seat, when the distance between the two pedals and the
ground is the same, the front knee should not exceed the toe.
But also can't sit empress dowager, in front of that leg crus and instep angle is not greater
than 90 degrees.
3. Handle height adjustment: after adjusting the seat, adjust the handle to a slightly higher
height than the seat; keep the waist and back as straight as possible, especially for the
obese and the weak core. If not used properly, the lumbar spine may be injured.
4. The shoelace must be tied, and then put into the fixed sleeve of the foot, and fasten the
tension belt, which can let you put more on the pedal when you exercise. The muscles in
exercise are more effective in pedaling.
Third: the right posture of the exercise bike

8
The wrong riding posture will affect the movement effect and cause harm to the body. It's like
bowing the waist, leaving the legs off, and pedaling is not standard, so it belongs to the
incorrect posture during riding.
Correct sitting posture: lean forward, arms straight, abdomen tight, abdominal breathing
method, legs parallel to the vehicle beam, knees, hip joint coordination, pay attention to the
rhythm of riding.
Correct trampling posture: correct pedaling should include: trampling, pulling, lifting and
pushing four coherent movements. The foot moves down first, then the calf retracts
backward, then raises upward, finally pushes forward, thus just completed a circle. Good
pedal rhythm not only saves physical energy consumption, but also improves speed.
Fourth: the right speed can be used for cycling
Frequency and intensity are the basic principles of exercise. At first, it is suggested that you
can find the right frequency, and then increase the amount of exercise. The average person
pedals about 60 to 80 times per minute. Warm up at low speed for each ride, and then
moderate and high frequency cycling for more than 20 minutes may cause slight sweating.
Fifthly, the purpose of different riding methods is different, but we should act according to our
ability. If you feel unwell, please stop training
1. In order to train to lose weight
For those who want to lose weight by bike, you can use aerobic cycling, which is to adjust
the feeling of resisting body load without exerting force. The intensity of this exercise should
be moderate, generally more than 30 minutes, in order to decompose fat. Therefore, the
best time to ride is 30 to 40 minutes, with a heart rate of 100-110 beats / min.
2. In order to train muscles
Exercise by bike to build muscles. Choose easy resistance, slow warm-up for 5 minutes,
then as a high-speed ride for about 5 minutes with a heart rate of 170-180 beats / min, and
then gradually slow down for 5-10 minutes so that the heart rate returns to 100 beats / min or
less. As a group, you can even do several groups and arrange a 3-5 minute rest between
groups
