Why do you lose your strength when the weather is hot?

This is related to what Chinese medicine calls "Qi", which is often combined with "Force".

According to your analogy, when doing push-ups, the first 40 people may change their breath 2-4 times. If you have done it, you should know that when you breathe, there will be a short pause (the more you do it, the more energy you consume, and the longer you pause).

But when you get to the 40th (assuming this person is close to the limit) and need to take a breath, your "strength" is almost used-just like the work of physical theory, a person's strength is limited-when the 40th person needs to take a breath, his will is often weak and his physical strength is too high, so he often stops.

Of course, if you insist on doing one or two more things, that's fine. The same is true of the so-called gas-nourishing exercise-when a person continues to persist without "strength", the exercise effect is often the most obvious, because after persistence, you will further nourish your gas, thus achieving the purpose of exercise-so when we exercise, persistence and breaking through the limit are not only opportunities to cultivate perseverance, but also opportunities to nourish your gas and replenish your body.
