Rubber-coated dumbbell refers to all-plastic structure, and its price is lower than that of electroplated dumbbell. Ordinary packaging mostly uses recycled plastic, which has a pungent smell and is easy to deteriorate after a long time, which is not good for the body. High-quality packaging mostly uses asphalt, which has a small smell. Because of the fine workmanship, it is difficult to distinguish between ordinary packaging and high-quality packaging.
The dumbbell covered with cast iron is covered with rubber, and the inside is made of cast iron. The outer coating is also divided into ordinary coating and high-quality coating. Dumbbells with the same weight and volume are relatively small and affordable.
The price of electroplated dumbbells is higher than that of packaged dumbbells. Electroplated dumbbells are brightly colored, never fade, and have no irritating smell. They are generally used for family fitness.
Baking dumbbells are made of high-quality cast iron and baked by electroplating. The painted dumbbells are more beautiful in appearance and more expensive than electroplated ones, so they are suitable for professional fitness centers.
Generally speaking, the dumbbells used for fitness are detachable and have different weights, which can be adjusted by themselves according to different dumbbell exercise methods and dumbbell fitness stages.
1. The price of black rubber-coated dumbbells is generally 6-7 yuan/kg, but it is not recommended. Dumbbells covered with rubber and sticks covered with rubber are easy to break over time, and harmful gases are volatilized.
2. The price of electroplated dumbbells is generally 9- 10 yuan/kg.
A pair of dumbbells with good color and material have a desire to exercise after reading them, so the choice of dumbbells should be satisfied first, and the price is second to the strong body. After all, it is a one-time investment. At present, the marked weight of most dumbbells in the market is inconsistent with the actual weight (including the weight of dumbbell rods), and it is normal to add or subtract 2 kilograms, so ask the shopkeeper about the actual weight of dumbbells before choosing to buy them.
