Recumbent arm flexion and extension: (triceps brachii) Place the straight handle device at the lower joint, lie on the training table, and keep the head away from the inside and outside of the instrument ruler. Hold the crank with your hands shoulder-width apart and bend your arms above your face. The flow of the shoulder joint is still, bend the elbow to lower the crank to the forehead, stop before contact, and then curl your arms hard. Note that the elbows should be clamped inward and the arms should always be perpendicular to the sky. The standing rope handle presses down (triceps brachii) to connect the rope handle to the upper pulley. Facing the instrument, hold one end of the rope handle with both hands. Tighten the steel wire further before. Bend your elbows, move your hands up to the front and middle of your body, and your forearms are parallel to the sky. Keep your arms flowing and press down on your forearms until your hands are on your thighs. Repeat after rapid recovery. Note that you are trying to squeeze the triceps to curl your arm. 1. Sit with one arm bent (biceps brachii). The crank flows on the left lower pulley, and the exercise stool is placed half a meter away from the equipment. Sit down and hold the crank in your right hand. Lean forward, curl your right arm, rest your back on the inner thigh, and palm up. Hold your left leg with your left hand. The right arm is firm. When bending, lift the crank to the shoulder. Recover after a little progress. Switch to the other arm after realizing the digits on one side. Pay attention to the expansion of biceps brachii at the peak of action. The hand-operated device inserted into the chest of the low pulley (shoulder muscle and brain muscle) is at the low-end joint of both sides of the tension spring of the door frame pulley. Stand at both ends and hold the crank forward with the palm of your hand. Always take a step away from your left foot and curl your arm to tighten the wire. Elbows bend slightly, and hands pull the crank to the chest along the arc. After a little progress, rapid recovery will be repeated. Pay attention to expanding the chest muscles at the highest point of the action. The upper pulley is connected with the crank by inserting it into the chest (pectoral muscle), and its figure is opposite to that in the last exercise. Hold the crank with your palm down, lean forward slightly, keep your back straight and bend your elbows slightly. Pull the crank back and forth with both hands, reach the front of the abdomen and touch each other, and gradually recover to the elbow slightly higher than the shoulder. Start the next movement, and pay attention to the loss of proper traction on your shoulders and chest before the movement begins. One-arm sea election (shoulder muscles) crank device is on the lower right pulley. Hold the crank forward with the palm of your left hand. The figure is ~ cm away from the instrument, kneeling on the ground, so that the pulley is slightly behind the shoulder. Choose the crank with your left hand, so that the elbow joint is degree, the arm is parallel to the sky and the forearm is vertical to the sky. Hold your hip with your right hand and push the crank upward with your left hand until your arm is completely curled, but you don't need to lock your elbow. After gradually recovering, I repeatedly realized that one side was replaced by the other. Be careful not to raise your elbow over your shoulder when recovering. Stand on the boat with the rope handle (the middle and upper part of the back muscles), and the rope handle is connected to the low pulley. Stand facing the instrument and hold both ends of the rope handle with both hands. The knees are slightly bent, and the lower body is bent from the hip joint to the sky. Abdomen in, back straight, arms holding back muscles stretching forward and bending with steel wire, elbow bending, pull the rope handle to the middle of the body, elbow as far back as possible and then gradually recover, and start the next action, so as not to let the weight fall. Pay attention to the chest during the action. One-arm pull-down (middle and upper part of back muscle) crank is connected with the upper pulley. Hold the crank forward with the palm of your left hand. Kneel down. Kneel down. The right shoulder is on the left side of the pulley. The back muscle pulls down the handle to the outside of the shoulder, and the elbow joint is vertical to the side. In the process of pulling down, the palms turn inward and the shoulder blades gather towards the spine. Gradually resume the repetition and switch to the other side. Pay attention to keep a stable figure during the initiative. If the car is high and low, you can do it standing. The standing bend (biceps brachii) connects the straight handle with the low pulley. Stand facing the instrument. Hold the crank with your palms up and your arms hanging behind your thighs. Your left foot is shoulder width, stand up straight, and your knees are slightly bent. Then bend down and lift the crank to the front of the brain, make progress at the peak and expand the biceps brachii vigorously. Gradually recover and repeat. Note that the elbow joint moves to one side of the body, but it is not important to hold it. What should we do? Choose pulley tension springs with various performances. Pulley tension springs are as changeable as dumbbell exercises and as simple as instruments. The change of pulley position and various cranks enable you to choose from dozens of exercises aimed at the whole body skin. The exercise of adapting the body to the instrument is generally the action of Euclid's imaginary trajectory. The pulley tension spring can be changed according to your body length and hard position, so it is more suitable for the width of each group of actions. Let more skin participate in the task. The immobile property of pulley tension spring requires you to support the automatic muscle with the stabilizing muscle, so many small muscle groups also lose the training opportunity. Therefore, most pulley stretching exercises are stopped standing, because the whole body skin includes gluteal muscles. Lumbar and abdominal muscles and leg muscles are involved in the task. The load of pulley tension spring can be easily changed by moving the plug, and it is also very convenient to replace the crank.

For those harmless little mistakes.

Be generous and give each other a room for adjustment and correction.

Not only did you get heartfelt gratitude.

And your unwavering support.

It won't fight back unless it has to.

You will put all your eggs in one basket.

Although China people advocate the golden mean.

But in real life, they go to extremes everywhere, and that's why.

Its core meaning is the golden mean.

Let the world not be extreme, don't go to extremes. There is a saying that a young civil servant graduated from a prestigious school and was brilliant.

In the end, they ended up being killed-they didn't fall by the enemy's sword.

There is no place to sell regret medicine in the world, even if there is regret, it is too late.

Their glorious lives.

So it ended hastily.

How can we not understand such painful advice written in blood and brain?
