Novices can wear gloves, but after long-term training, their hands are covered with cocoons, so it doesn't matter if they don't wear gloves. If you don't like the cocoon on your palm, you can consider wearing gloves for long-term exercise. In addition, if the wrist is injured, it is recommended to wear a wristband, which can play a certain protective role.

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 your dumbbell fitness is to gain muscle, do 8RM to 12RM dumbbell movements every day, and do about 3 to 8 groups for each movement; If the purpose of your dumbbell fitness is to keep fit, do the relevant dumbbell movements 15RM to 20RM every day, and do 5-6 groups for each movement.
