1, repetition frequency of reducing fat and increasing muscle is 8- 12RM, and strength improvement is 1-6RM. The training orientation is different, so the significant strength improvement of reducing fat and increasing muscle is not significant.
2. Strength also includes the coordination of nervous system and the standard level of posture. Weightlifting stipulates that the nervous system has strong fund-raising ability and can use the muscles that can be used all over the body harmoniously. Fitness is to isolate muscles, that is, to stimulate isolated muscles with appropriate net weight as much as possible. Bench press only uses muscle strength as far as possible, while weightlifting stipulates that all upper bodies work in coordination.
3, posture norms and your own cognitive problems, in fact, are similar to the last one, that is, posture norms and self-perception ability are improved, you will better isolate muscles, others use the muscles of the whole body to do a dumbbell bend, you only use biceps, although your net weight is not as good as his, but your actual effect of reducing fat and increasing muscle is better than his.
4, the habitual problem of strength, strength is only a special tool for fitness, you can use the whole body before lifting the hanging object, but later you get used to it, you may only be able to lift the hanging object involuntarily with your abdomen, and you feel that your strength has not improved.
5. The decrease of body fat rate makes muscles look big, but in fact, the level may be lowered, which is very common in groups that can't be repaired after training. Only the decrease of body fat rate can make muscles bigger.
