The weight of dumbbells (single) is generally in kilograms, and the common ones are 2.5, 5, 7.5, 10, 12.5, 15, 17.5, 20, 22.5 and 25. As for which weight dumbbell is most suitable for everyone, there is no standard comparison table, and there is no complete comparison relationship between strength and age.

Generally speaking, for male novices who think their strength is not great, it is suggested to start with 2.5KG or 5KG, because rushing too fast may hurt their muscles and lose their good mood for exercise. There is a professional word called RM, and RM in dumbbells is used to indicate the number of repetitions, which is the maximum repeatable value.

5RM is the weight of dumbbell that can be lifted up to 5 times continuously, and 10RM is the weight of dumbbell that can be lifted up to 10 times continuously. For example, if you lift it to 10 times with 15KG in training, then 10RM means 15KG. Then this method is also suitable for testing the weight of your most suitable dumbbell.

For example, for a novice male, the weight of 10RM is the most suitable for you, but after you exercise for a period of time, you can try to exercise with a weight of 5RM.
