There are many kinds of fitness equipment, such as horizontal bar pull-ups and parallel bars arm flexion and extension, which are all good ways to exercise strength. Bouncing fitness equipment uses running or jumping in situ to help keep legs bouncing (not recommended for the elderly). Sensitive equipment can practice the reaction ability of hands and feet, brain and the coordination ability between limbs and brain. Flexible devices increase the flexibility of joints and make the whole body more flexible. Endurance equipment is divided into aerobic endurance and anaerobic endurance. Most outdoor endurance equipment is aerobic endurance equipment, such as treadmills, exercise bikes, elliptical machines and so on.

When using the equipment, please remember the "Four Precautions".

1, don't exercise excessively. People who often take part in physical exercise can appropriately increase the amount of exercise. Generally, the pulse does not exceed 1 10 times per minute, and the maximum pulse does not exceed 120 times per minute. Old comrades who seldom or never took part in physical exercise in the past should first choose sports that suit them.

2. Get ready before exercise and warm up for about 10 to 15 minutes. This can prevent neck twisting, waist twisting and nerve injury.

3. Do some tidying activities after exercise. Because people's capillaries will expand after exercise, if people sit still on the ground and the blood can't return to the far end of the heart, they will feel weak heart, chest tightness, blood pressure and old comrades who have suffered from heart disease. After exercise, they must take a walk and buffer 10 minutes or so.

4. Master the exercise time. Old friends each time about 40 minutes, generally not less than 30 minutes, not more than 1 hour.

The horizontal bar is 2.55 meters high.

The whole set of horizontal bar movements consists of swinging movements, which are continuously completed by various grip methods, including big loop, near bar movements, turning around the longitudinal axis of the body, flying movements and so on. Two single-arm swings are allowed through the drooping surface of the rod. The horizontal bar has special requirements, such as difficult flying movements.

Horizontal bar events are often arranged at the end of gymnastics competitions, because parallel bars are the most ornamental events and are usually the favorite of the audience. At the same time, the horizontal bar is also the most dangerous, because almost all horizontal bar movements are non-stop loop movements, at least one movement of leaving the bar with both hands (and then grabbing the bar again), at least one movement of facing away from the horizontal bar, and at least one rotation movement.

The grip of the horizontal bar is very important. * * There are three kinds: front grip (palm facing forward), back grip (palm facing backward) and cross grip (one hand holding forward and one hand holding backward). What grip to use depends on the direction of different movements. No matter which grip you use, the most important thing is that your thumb must point in the direction you move. Otherwise, it is easy to fall to the ground because you can't catch the horizontal bar when you loop. For example, the front loop ball should be held with the thumb pointing forward; In the back circulation, hold it backwards and point your thumb backwards.

The horizontal bar is also one of the most exciting parts. Many athletes can fly to a height of nearly four meters and do some dazzling somersaults and turns. At the same time, finally landed firmly.
