Commonly, according to sex, age or occupation, the weight of a dumbbell is different. Women generally use 3-5kg, men use 5kg-8kg, and bodybuilders use much heavier dumbbell. People have various dumbbells individually and use them respectively. The weight of existing dumbbells cannot be changed, so users need to buy different dumbbells in different weight. Users can adjust the weight of the dumbbell from 3kg to 40kg, so they need only one dumbbell when they do exercise. If gyro from the gyroscope turns around, users can feel the weight increase because it causes the centrifugal force. The faster it turns around, the heavier the user feels it. Anyone that uses the power dumbbell can adjust the weight of the dumbbell. This dumbbell design is economic and has a high spatial utilization because users do not need to buy different dumbbells in different weights for their own exercise.
