The arm flexion and extension of parallel bars is mainly to practice pectoral muscle, triceps brachii and deltoid muscle (toe), as well as latissimus dorsi and trapezius muscle. The equipment needed is the best parallel bars. Early exercisers are not strong enough, so they can choose benches, beds and other living furniture and take the same action (because stepping on the ground can reduce the weight load). This kind of fitness is not suitable for people with great fitness.
The general process of the movement is: hold the parallel bars with both hands, support your arms on the parallel bars, keep your head upright and shoulder-height, keep your trunk and upper limbs vertical to the parallel bars, bend your knees, and overlap your calves with your ankles. The elbow joint bends slowly and the shoulder joint flexes, so that the body gradually descends to the lowest position. Pause for a moment, raise your arms to restore, and pay attention to exertion.
Fitness strategy
Fitness is a kind of exercise, such as all kinds of unarmed aerobics, rhythmic gymnastics, rhythmic gymnastics, and all kinds of self-resistance movements. Gymnastics and yoga can enhance strength and flexibility, increase endurance, and improve the ability to coordinate and control all parts of the body, thus making the body strong. If you want to relieve stress, exercise at least three times a week and don't overdo it.
Swimming, brisk walking, jogging, cycling and all aerobic exercises can exercise the heart. Aerobic exercise has many benefits: it can exercise the heart and lungs, enhance the function of the circulatory system, burn fat, increase vital capacity, lower blood pressure, and even prevent diabetes and reduce the occurrence of heart disease. The American College of Sports Medicine suggests that if you want to know whether the intensity of aerobic exercise is appropriate, you can test your heart rate after exercise.
