The arm stick is a spring with handles at both ends and a strong spring in the middle. A kind of sports equipment that mainly exercises arm strength is a black spring with the thickness of corncob sold in sporting goods stores, which exercises your forearm strength and wrist strength.

Function;

The first arm muscle (deltoid muscle, biceps brachii) and pectoral muscle. There used to be an arm stick in the bedroom. A very thin buddy has been practicing for a while, and his chest is much cheaper than having chest muscles. Exercise arm muscles, choose the exercise mode of arm exerciser, and pay attention to the use mode: 1. Bend your arm and bend the spring hard at the back of your neck. 2. Put your arms forward, bend the spring upward, and then relax. 3. Keep your arms close to your chest, bend the spring, then straighten and slowly relax. 4. 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. 5. Hold the spring tightly when your arms die, then straighten down and bend gradually. Concern: 1. Before use, please check whether the adjacent parts of the arm are stable and not loose. 2. Please choose the arm strength device suitable for your body level, so as not to strain your muscles. 3. When in use, fasten the safety belt on the handle of the arm strength device on the wrist, as shown in the left figure. 4. When using, you should choose a relatively spacious venue to exercise, so as not to hurt people. 5. It is suggested that children under the age of 12 should not use arm sticks: the arm sticks of chest muscles, shoulder muscles and back muscles have significant effects on strength, but have no significant effects on muscles. I used to train 50kg arm sticks in each group, and the 10 group worked for two months every day, but I didn't see a piece of meat for many years. So I don't know which to practice. Push-ups are the simplest.
