Strength training also has different purposes.

The purpose of exercise is 1 absolute strength 2 muscle mass 3 muscle endurance.

Strength training has three elements, intensity, number of groups and interval time!

Different combinations have different exercise effects.

First of all, introduce a concept, strength training intensity "RM"

The intensity of strength exercises is expressed by the number of repetitions of maximum strength (RM). For example, if you can only lift a weight of 60kg once with maximum strength, then this weight is called 1RM. Different RM and strength training groups have different effects on muscles.

Group 3-6RM 3-6 mainly develops the absolute strength of muscles.

Group 8- 12RM 3-6 mainly developed muscle mass.

14-20RM 4-6 group, mainly developing muscle endurance.

Now let's look at the landlord's problem.

It is obvious that the former aims at absolute power.

The latter! I think the landlord may want to know the effect of the latter, so compare the above data and you will know its endurance.

The landlord's question did not mention the number of groups and the interval of exercise.

It can be seen that the landlord's exercise depends entirely on his feelings and he doesn't know enough about exercise.

If only by feeling, it works! But if you can combine some knowledge, the effect will be better!

It is suggested that the landlord can buy a sports book, which is not professional but general.

There is the Training Manual of Students' Physical Health Standards published by People's Education Press.

Many middle schools have it. Although I am a middle school student, I am very good at basic introduction, or buying a college physical education. It may not be so detailed, but it is very helpful to improve after having a foundation.
