The weight comparison table of men's dumbbells is a fixed dumbbell, which is divided into light dumbbells and heavy dumbbells. The light dumbbells weigh 6, 8, 12, 16 pounds (one pound equals 0.45kg) and the heavy dumbbells weigh 10, 15, 20, 25, 30. Adjustable dumbbell-the shape is slightly different from the fixed dumbbell, and it is made by installing round iron pieces with different weights at both ends of the handle. These round iron sheets can be increased or decreased as needed. This dumbbell can also be made into a two-handed dumbbell with a round iron bar passing through a small barbell.

Dumbbell precautions

Joint activities, warm-up and muscle stretching should be done well before dumbbell fitness (the time is about 10 minute), and small-load exercise should be done before each exercise to make the target muscles enter the fitness state. After exercise, do muscle stretching and finishing activities (don't just sit down and relax), and don't eat, bathe or supplement food for half an hour.

Do a detailed plan for dumbbell fitness, don't practice blindly, and the longer you practice, the more often you practice. If you are thin, you need to increase aerobic exercise or do less weight and more times.

Breathing rules: If you are not used to breathing at first, you should learn it eventually. It is recommended to exhale when exerting strength and inhale when recovering. Never hold your breath.
