Muscle training itself is also a process of increasing strength, but pure strength training and physical fitness cannot be confused.

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. Novices can do 8 to 12RM load, and each group can probably do 8 to 12 load. Each group should rest for no more than one minute, and each movement should rest for no more than two minutes. Warm up for 10 minutes before doing the following exercises, and then you can run.
