Dumbbell Dumbbell is a simple instrument to strengthen muscle strength training.
Its main material is cast iron, and some are covered with rubber.
Used for muscle strength training and muscle compound action training. Patients with low muscle strength due to sports paralysis, pain, long-term inactivity, etc. Holding dumbbells, you can use the weight of dumbbells to actively exercise against resistance and train muscle strength.
Dumbbells can train a single muscle; If you increase your weight, you need the coordination of multiple muscles, and it can also be used as a kind of muscle compound action training. Exercising upper limb muscles is dumbbell's specialty, but dumbbell can also exercise waist and abdomen muscles. For example, lifting dumbbells with both hands behind the neck during sit-ups can increase the load of abdominal exercise and improve the exercise effect; When doing back flexion and extension exercises, dumbbells can also be used to increase the load of back muscles and stimulate the growth of back muscles; Holding dumbbells can exercise internal and external oblique muscles; Holding dumbbells, arms straight forward and lifting sideways can exercise shoulder and chest muscles; In addition, dumbbells can also exercise lower limb muscles, such as squatting with one foot and jumping with both feet.
As we all know, it is necessary to analyze the adaptability of centrifugal force when conducting astronaut physical fitness test. Centrifugal force can make objects with small mass gain several times more kinetic energy than usual and continue to generate inertia, so the power of centrifugal force can not be underestimated. The fitness equipment industry has been exploring how to apply this instantaneous kinetic energy to product design.
Under this trend, the newly developed kinetic energy dumbbell came into being. Breaking through the heavy feeling of traditional dumbbells, the weight is only 0.85kg, making it easier to exercise and keep fit. It combines the functional characteristics of wrist ball and dumbbell to provide key muscle training and full-body exercise effect. Compared with the mainstream dumbbell products in the market, strength, space and kinetic energy dumbbells have many advantages: the products are imported from Taiwan Province Province, with international patents, and have won international awards for many times, selling well in Europe and America; In addition, kinetic energy dumbbells are unisex, and users can add dumbbell pieces as needed to combine aerobic exercise with anaerobic exercise; Dumbbells are light, beautiful and compact, and are deeply loved by women. The simple design that does not occupy space makes the dynamic dumbbell more detachable and easy to carry and store. It is the simplest and most convenient innovative sporting goods for busy modern people, allowing people to stay in hotels and travel at any time.
