How does fitness work? From the perspective of "target muscle group", maybe you usually do resistance training for muscle building in the gym. In fact, we must clearly realize that resistance training not only emphasizes the gradual load (weight), but also emphasizes the depth of muscle stimulation.

For beginners, the muscle performance is inferior to the physical fitness level, and the muscles are often exhausted, but the breathing is still normal (that is, the heart rate is often said, the value may not be particularly large). Through day-to-day training, muscle strength and endurance are gradually improved, and gradually you will find that when you want to be truly "exhausted", you will be very panting after each set, because at this time your heart rate Has soared.

From another perspective, your movement ability is not enough to use heavy weight (weight within 6RM). For example, in order to maximize hip training, we do hip-driven squats. When you do 12RM, your brain can link nerves and muscles to complete the squat. But when doing 6RM weights, just When you squat to the first one, the movement has been deformed, and the hips are completely unable to exert force. This is a typical case where the movement ability is not enough to support the muscles using heavy weight.

No matter what the action, when using heavy weight, the trunk needs to be rigid and stable. The muscles of the entire trunk contract statically, and even enter the tile breathing state; this state will make the heart rate soar, and each group can make people breathless. , Has also entered the state of "feeling very tired" as you said. Therefore, on the premise of ensuring that the quality of the action is high, it takes a certain number of training years and training level to train yourself to cry. However, many people do not have the ability to practice crying. This is really a cruel reality.

How does fitness work? In summary, if resistance training is not tiring, it means that the weight used is not enough to mobilize the stability of your whole body. So why not try, under the premise of ensuring the quality of the movement, use twice the original weight, even if it is a dumbbell curl, you will unconsciously tighten your body and "hold your breath."

Try it, just find this tired feeling, don't blindly put on the weight. Because... (babble), if the action can't serve the purpose, no matter how heavy it is, it will be a waste. So don't think that if the weight is heavier, it is the practice. At most, the physical work has increased.
