Muscle carving experts effectively beautify muscle lines and contours, increase the three-dimensional sense of muscles, and can exercise arm muscles and chest muscles well, which is an essential fitness equipment for shaping men. Because of its small size, no space occupation, convenient exercise and good effect, it has been favored in family fitness equipment for many years and is a sharp weapon for family fitness. Usage: pull your arms forward into a straight posture, bend your elbows slightly, and the height should not exceed your eyes. Stretch to both sides, and don't move back and forth too much to avoid exertion. If not, reduce the spring to ensure the action is in place. The pull-up action is the same as before, but the height is above the head, and it feels like pulling to both sides. When the main training is in the chest, the spring can be appropriately enlarged than the normal position. Stand with one hand raised in parallel, step one end of the spring under the right foot, hold the spring tightly at the other end, keep the upper arm still, forcibly lift the forearm upward and stretch it up and down repeatedly. The defender pulls up the inspection stand with his feet parallel and his legs apart. Pull the two hand-held tensioners to the rear sides repeatedly. This action is mainly shoulder training. Stand with your feet staggered, in a back position, with your legs apart. Pull the two hand-held tensioners up and down at the back, gently relax after reaching the limit, and repeat. Advantages of using biceps brachii biceps brachii is a muscle with two muscle heads, and its main function is to bend the arm. Another muscle, the brachialis, is also used when bending the arm. However, the brachial muscle can only be exercised when doing some forearm lifting exercises, such as bending the high-position puller or anti-high-position puller toys. In addition, the brachioradialis muscle, the main muscle of the upper forearm, also plays a lot of roles in arm bending. The brachioradialis muscle can be strengthened by lateral bending of the stretcher. Precautions for use 1. Don't wear sharp and valuables when using the stretcher, so as not to affect the movement and cause injury or unnecessary loss.
4. Before using the wire spring tensioner, check whether the hook structure and installation of the wire spring are firm, so as to avoid slippage and injury accidents.
3. The Zhang Liqi of the wire spring should not be stretched for too long, otherwise it will make the wire spring lose its elasticity.
4. If the steel wire spring stored for a long time has rusted, don't use it again to avoid breaking during pulling.
5. Before using the steel wire spring tensioner, one end of the tensioner should be firmly fixed on other objects to prevent injury accidents caused by slipping or sudden rebound.
6. Wear long-sleeved sportswear and sweatpants when using a wire spring stretcher. Don't cling to the body of the steel wire stretching machine to prevent the steel wire spring from pinching the skin and hair when stretching and contracting.
Once, when using the wire spring tensioner, each wire spring must be hooked on the big ring and pulled by hand holding the handle. Don't pull with several big rings, in case the force is too concentrated on the wire spring ring, which will cause the wire spring to break.
8. After the action is completed, the spring should be controlled to return slowly by muscle strength, which can not only avoid the collision and overlap of the spring steel rope, but also give full play to the unique advantages of the tensioner's "retreat" movement, so that the muscles can be stimulated to the maximum extent, thus achieving the best sports effect.
