For fitness white, it is necessary and necessary to buy dumbbells. You can come here from time to time at home, but there are many kinds of dumbbells, including rubber-coated dumbbells, plastic-impregnated dumbbells, electroplated dumbbells, painted dumbbells, sponge dumbbells and water-filled dumbbells. What's the difference between them?

You don't want to build big muscles, but you also want to make your muscles thinner and stronger. Actually, you can buy dumbbells.

In addition to the heavy and bulky dumbbells, there are more convenient and lightweight dumbbells in the gym. More suitable for women, or the elderly and children to train. There are hundreds of dumbbells on the market. How do you know which one is right for you?

There are six kinds of dumbbells for your reference.

Dumbbells are covered with a layer of rubber, and filled with some stone powder or cement instead of iron, so they are bulky and will smell of rubber after a long time, and may harden or crack even if it is too cold in winter.

Immerse the dumbbell iron block in plastic water until the shell is covered with PVC or PE. The advantage is that it is a plastic outer layer, so it is rich in color, not easy to fade at ordinary times and has a long service life. In addition, it is light in weight, which many girls will use when strengthening training.

The material is cast iron and the surface is electroplated. This kind of dumbbell has high density, high hardness, wear resistance and smaller volume than the packaged dumbbell. Generally speaking, the one with better polishing degree should be chosen, because it is only coated with a layer of metal or alloy to prevent corrosion. If you choose poor quality, it is easy to peel and rust.

Cast iron is painted after electroplating, which is resistant to falling and wear and has a long service life. Most of them are supplied to gyms, belonging to a relatively high-end type, because the production of painted dumbbells requires high-quality cast iron and painting technology, and requires high technical requirements besides aesthetics.

Another advantage is that the dumbbells used for baking paint can usually be disassembled, and the weight can be adjusted according to the training needs and exercise methods.

Dumbbells are protected by a layer of sponge outside the iron body, which is safer and easier to hold, but because of their small weight, the heaviest weight is only 2 kg, which is suitable for novice Xiaobai.

Lightweight and convenient to carry, the water quantity can be adjusted at any time, and mung beans or fine sand can be added. Most of them are plastic shells and weigh 1 kg.

Therefore, these six kinds of dumbbells can be purchased according to demand, but the following three places need to be paid attention to before purchasing.

What is the right weight? If the weight that the dumbbell can lift is 10 kg, then the optimal weight of the dumbbell is 6.5-8.5 kg.

We should not blindly pursue multiple groups, but do it in place, so as to effectively stimulate muscle tissue and achieve the purpose of increasing muscle.

You can set your own rhythm and practice each group of movements, which can shorten the interval of movements. 1-2 minutes, rapid exercise can make muscles enter anaerobic exercise and also achieve the purpose of reducing fat.

Dumbbells are just an aid and should not be done more. They are mainly used to exercise local muscles, because using dumbbells only increases muscle burden to achieve high-intensity exercise effect, or needs to be combined with other equipment for all-round training.
