I got up in the morning and drank a big glass of water. How does it hurt when my stomach leans to the right during running? Can I drink water before running? How much is the best to drink?

From my experience, I guess you don't have a stomachache.

It hurts under the ribs at the bottom, right?

This is not a matter of diet, but a matter of your constitution.

People who have just started to practice long-distance running often only pay attention to increasing the breathing frequency, but ignore adjusting the breathing depth, which leads to the acceleration of the contraction frequency of breathing muscles and the tension of breathing muscles, thus causing spasms. The spasm of respiratory muscles can directly stimulate sensory nerve endings, thus making people feel pain. People with weak constitution are particularly prone to this situation.

Let me talk about my experience:

1. Control the running speed.

Run slowly, run fast, even the fastest speed at first can't be fast. You've only been running for two weeks, and you still have a long way to go. If you are in good health, you can accelerate after 1 ~ 2 months. If you are weak, it will take another two months. Breathing muscles are not easy to exercise.

2 control the breathing depth and frequency:

Consciously control your breathing. You can count your steps, that is, you can run a few steps between breaths. If you are not used to it at first, just practice more.

Take a breath, hold your breath, and don't exhale. Hold 1 ~ 2 seconds before exhaling. Exhale speed should also be controlled slowly. After you get used to this breathing frequency, you can slowly extend your breathing time.

Last but not least, everything depends on the individual. You can ask yourself to be taller if you are in good health, and you can come slowly from the bottom if you are weak. I was like you five years ago. It hurts when running, but it doesn't matter now. Because I can not only control my breathing, but also get better and better every day in running.

A journey of a thousand miles begins with a single step.

I wish you success!
