Dumbbell is a simple device used to enhance muscle strength training. In this case,
Its main material is cast iron, and some outsourcing a layer of rubber. In this case,
It is used for muscle strength training, muscle compound action training. Due to motor paralysis, pain, long-term inactivity leading to low muscle strength in patients with hand-held dumbbells, dumbbell weight can be used to resist the resistance of active exercise, training muscle strength. In this case,
Dumbbells can train a single muscle; such as increasing the weight, you need to coordinate a number of muscles can also be used as a muscle compound action training. Exercise upper limb muscles is a good dumbbell, but dumbbells can also exercise waist muscles. Such as sit-ups in the back of the neck when the hands clenched dumbbells, abdominal exercises can increase the load and improve the exercise effect; for dorsiflexion exercises, the same can increase dumbbell back muscle load to stimulate the back muscle growth ; Holding a dumbbell body flexion or twist movement, can exercise abdominal, external oblique; holding a dumbbell straight arm before the move, lateral lift can exercise the shoulder and chest muscles; In addition, dumbbells can also exercise the lower limbs Muscle, such as hand-held dumbbell squat single foot, squat legs jump and so on.
As we all know, in the astronauts fitness test should be carried out when the centrifugal force adaptive analysis, centrifugal force can make the original quality of small objects instantly get several times larger than usual kinetic energy, and continue to produce inertia, so the centrifugal force can not be underestimated . Fitness equipment industry has been exploring the moment to enhance the use of kinetic energy to the product design.
In this trend, the newly developed dynamics of space kinetic energy dumbbell (kinetic energy dumbbell) was born. It breaks the traditional dumbbell bulky feeling, weighs only 0.85kg, sports fitness more easily The combination of wrist ball and dumbbell features, providing focused muscle training and body movement effect. And the market mainstream dumbbell products like the intensity of dynamic kinetic energy dumbbell has many advantages: the product is imported from Taiwan, with international patents, has won several international awards, popular in Europe and America; In addition, the kinetic dumbbell men and women Universal, the user Dumbbell can be added according to demand, the aerobic exercise and anaerobic exercise combined; dumbbell can carry, the appearance of beautiful small, well received by women. Simple design, so that the kinetic energy dumbbell with disassembly features, easy to carry admission, is the most convenient and convenient modern innovative sporting goods, so that people travel hotel, travel, ready to use.
Introduction to Folding
Dumbbells can train a single muscle; such as increasing the weight, you need to coordinate a number of muscles can also be used as a muscle compound action training. There are two kinds of fixed weight and adjustable weight. ① fixed weight dumbbell. Made of cast iron, the middle is the iron bar, the ends of the ball is a solid, light dumbbell weight of 6,8,12,16 pounds (1 pound = 0.4536 kg) and so on. Weight dumbbell weight of 10,15,20,25,30 kg and so on. ② adjustable dumbbells. Similar to the reduced barbell, put in the short iron bar at both ends of the round weight ranging from iron, about 40 ~ 45 cm, weight lifting or fitness exercises can increase or decrease the weight. Dumbbell exercises often do, you can enhance the muscles of various parts of the body strength.
In addition to iron dumbbells, there are wooden or plastic dumbbell. Practice, the use of wooden dumbbells or plastic dumbbell percussion, training practitioners of the coordination and rhythm. Can also be compiled into sets of wooden dumbbells gymnastics action show.
Folding exercise method
1, before practicing dumbbell to choose the right weight. In this case,
2, the purpose of exercise is to increase muscle, the best choice of 65% -85% load dumbbell. For example, if each can lift the load is 10 kg, you should choose a weight of 6.5 kg -8.5 kg of dumbbells for exercise. Exercise every day 5-8 group, each action 6-12 times, action speed should not be too fast, each interval of 2-3 minutes. Load is too large or too small, intermittent time is too long or too short, the effect will be bad. In this case,
3, the purpose of exercise is to reduce fat, the proposed practice should be 15-25 times per group or even more, each interval control in 1-2 minutes. If you feel that this exercise is very boring, you can practice with their favorite music, or follow the music do dumbbell aerobics.
Folding benefits
1, long-standing practice dumbbell, you can modify the muscle lines, increase muscle endurance, often do heavy weight dumbbell exercises, can make the muscles strong, strong muscle fibers, increase muscle strength. In this case,
2, can exercise upper limb muscle and waist, abdominal muscles. Such as doing sit-ups in the back of the neck when the hands clenched dumbbells, abdominal exercises can increase the load; hand dumbbells do body lateral flexion or twist, you can exercise intra-abdominal, external oblique; holding dumbbell straight Arm lift, lateral lift can exercise the shoulder and chest muscles. In this case,
3, can exercise lower limb muscles. Such as hand-held dumbbell squat single foot, squat legs jump and so on.
