Generally speaking, in the field of fitness, "RM" is a word with unit nature, which is used to describe what kind of weight should be chosen during training.
For example, the coach said, "To achieve the ideal muscle gain effect, please choose the group of weight 10RM, 10 and * * * 6." This means that in order to increase the volume of biceps faster, it is recommended that you choose the weight that cannot be lifted after 10 bending (this weight is 65438.
It can be seen that "RM" is an expression of weight selection standard relative to the trainer himself, but at the same time, sometimes RM also takes into account the times of each group. In this case, the trainer will often do his best in the plan, so each group will practice x times with the weight of xKG directly.
General extended data:
1-6RM is mainly used to exercise maximum strength.
8- 12RM is mainly used to exercise muscle mass.
15RM or above is mainly used to exercise muscle endurance.
However, it does not mean that the weight of 1RM will not increase the muscle mass, but the effect is not as obvious as that of 8- 12RM or the change of maximum strength is more obvious.
