1. Arm strength device, also known as grip strength stick, is used to exercise arm muscles, mainly to exercise arm strength and chest muscles, and to assist wrist strength. Arm strength device is a kind of exercise equipment for forearm wrist flexor, which is dangerous to some extent. According to the size of the force required when using, the common armrests are divided into different levels, generally divided into 20, 30, 40, 50 and 60 kg, which refers to the force required by Bai Wan armrests.
2. Spring stretcher is a kind of equipment suitable for mass fitness. The advantage of using a stretcher is that biceps brachii is a muscle with two muscle heads, and its main function is to bend the arm. Another muscle, the triceps brachii, is also used when bending the arm. However, only when doing some forearm lifting exercises, such as bending the high-position puller or anti-high-position puller toys, can the brachial muscles be fully exercised. In addition, the flexor brachialis, the main muscle of the upper forearm, also plays a lot of roles in arm flexion, which can be strengthened by lateral bending of the tensioner.
Is the figure-eight stretcher better or the spring stretcher? I am used to using springs. It depends on personal preference. There is no absolute good or bad.
I have a spring stretcher. Do I need to buy an arm? Dumbbells. Dumbbells can have more exercise methods. You can exercise muscles in many parts. And the storage time is very long. Arm strength device for a long time. Spring will get old.
Is it better to use double springs or single springs for arm strength? Arm strength device, double spring is good for arm strength, and single spring is bad for arm strength.
Which one consumes more energy, the spring stretcher or the arm stretcher? The consumption of spring tensioner is relatively large.
1, arm stick mainly exercises forearm strength. Of course, if the wrist does not turn, some movements will also use trunk strength, but it is not a good way to exercise trunk strength, and the range of trunk muscle activity is too small. The range of stretching exercise is very wide, and the core exercises are waist, back, shoulders and big arms.
2. The stretcher is a kind of equipment suitable for mass fitness exercise. The advantage of using a stretcher is that biceps brachii is a muscle with two muscle heads, and its main function is to bend the arm.
3, the arm strength device increases the muscle strength of the upper limbs, including the strength of the pectoralis major, shoulders, elbows, wrist joints, etc., which can make the upper limbs muscular and increase the arm strength. Improve physical fitness.
Is it better to use dumbbells or spring tensioners for arm shaping? Of course, dumbbells are good, and many muscles of the arm can be trained. The spring tensioner is useless.
Is it better to use a spring stretcher or a spring bar to practice chest muscles? Both effects are similar, mainly depending on the method of practice.
Spring stretcher, commonly known as chest expander, is designed for training chest muscles. Of course, spring tensioners can also help exercise other muscles.
Methods of chest muscle training:
1. Pull in a positive posture, stretch your arms forward, bend your elbows slightly (the same below), and extend to both sides with the height not exceeding your eyes. Don't move your body back and forth too much, so as not to lend your strength. If not, you'd rather reduce the spring to ensure the action is in place.
2. Pull up. The action is the same as before, but the height is above the head, and there is a feeling of pulling to both sides. Mainly exercise the chest, and the spring can be appropriately larger than the positive pull.
3, pull down, practice the chest and engraving, that is, put the spring on the navel and pull it to both sides, and the number of springs should be reduced to a minimum (not less than two).
4, staggered pull. The right arm is in the direction of the right shoulder and the left arm is separated in the direction of the left hip. Then change direction. That is, the left arm is pulled to the left shoulder and the right arm is pulled to the right hip. The spring line is biased to the vertical axis of the human body center. Each movement is divided into 4 groups, with the highest beat of 16 in each group, and springs can be added after increasing strength. Cooperate with other practice postures.
5. After the puller is put into the body, hold the handle of the puller with both hands, bend the elbow forward with the palm of your hand, and lift your arm sideways. Restore. Prone and lateral stretching can also practice chest muscles, and the effect is better.
Fitness with spring bar
Spring bar, also known as elastic bar, is a kind of fitness equipment that appeared in China in 1980s. The spring rod is 75 cm long and round.
