Where is the kettle bell? There are two kinds of classification, one is called classic kettle bell, and the other is called competitive kettle bell. The classic kettle bell is solid. Different weights have different volumes. For female fitness beginners, I still recommend the use of dumbbells, because the center of gravity of dumbbells is in their own hands, while the center of gravity of kettlebells is outside the body, which is more laborious to control. The key is that the kettle bell is relatively heavy and there are fewer actions that can be completed. The kettle bell pays attention to core training. The kettle bells used in the competition are hollow, and different weights and volumes are the same. Dumbbell is a widely used fitness equipment, which is inseparable from its physical properties. The density is high, and the center of gravity is in the geometric center. When you hold the dumbbell, you just control the center of gravity, which is very labor-saving to use and can also play a good exercise effect. And there are various actions that can be completed. Although the price per unit weight of kettle bell is lower than that of dumbbell, I prefer to use dumbbell. There are many safe modes, which can exercise more muscle groups. People who have no exercise habits at first, whether male or female, should not exercise indoors. A slow instrument will only accumulate dust. At first, the best exercise was not watching TV or playing mobile phone after dinner, three times a week, wearing sports shoes every other day, and walking for half an hour after dinner. When you get used to this intensity, jump rope and kick the key, jump rope 20 times and press the key 5 times. At this time, you can buy a dumbbell with 5% of its own weight instead of a kettle bell. The kettle bell is an ancient stone lock, cowhide belt and copper nail to protect the wrist. The training changes of dumbbells are bigger than those of kettle bells, and most of the movements of kettle bells can be done, so it is more suitable for training at home. And it is very cheap.
