Spring stretcher, commonly known as chest expander, is designed for training chest muscles. Of course, spring tensioners can also help exercise other muscles.
Exercise method of chest expander:?
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. The main training is in the chest, and the spring can be appropriately larger than the positive pull;
3. Pull down, practice chest stitching and carving, 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 pulling. The left arm is in the right shoulder direction, and the left arm is separated in the left hip direction. 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 puller handle 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.
Exercise method of arm strength device:
Bend your arm and bend the spring to the back of your neck;
Bend the spring forward and upward with both arms, and then relax;
Keep your arms close to your chest, bend the spring, then straighten out and slowly relax;
Stand with your feet apart, bend your right elbow, bend the spring with your left hand, then bend your left elbow and bend the spring with your right hand;
Put your arms behind your back, hold the spring tightly, and then straighten down and bend gradually;
The pursuit is quantity, not weight.
Of course, no matter what kind of training should be carried out with aerobic exercise, the effect of increasing muscle and reducing fat is more obvious.
