The weight of dumbbells needs to be adjusted according to different people and different movements, because people with different weights are suitable for different weights, and even different exercise movements need to adjust the appropriate corresponding weights.

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. The weight of 8 to 12RM is most suitable for beginners, that is to say, beginners can adjust the weight to 8 to 12 times in each group, which is close to exhaustion. Each group should rest for no more than one minute, and each movement should rest for no more than two minutes.

Precautions:

Exercise time and meal time should be separated by 30 minutes to an hour;

You should run for a few minutes to warm up before exercise.
