In bodybuilding theory, RM is used to indicate the maximum number of repetitions that a load can do continuously. For example, an exerciser can only lift a heavy object five times in a row, so the heavy object is 5RM. If the purpose of dumbbell fitness is to increase muscles, do dumbbell movements from 8RM to 12RM every day, with 3 to 8 groups for each movement and 8 to12 for each group; If the purpose of dumbbell fitness is to keep fit, do dumbbell movements from 15RM to 20RM every day, with 5-6 groups for each movement and 1520 for each group. For girls, 15RM to 20RM is more appropriate.
