What is the difference between running and HIIT? When running, you can think about a lot of things in a wild way, or you can completely empty yourself, not thinking about anything, but only paying attention to my breathing.
After a period of time, I will improve my level and see if my feeling will change when my physical fitness recovers to the peak state…
I just thought about how to do this action well, but it hasn’t ended yet.
Even the breathing doesn’t need to be controlled, just go running.
I don’t know because of my current strength and physical fitness.
It is also because high-intensity interval training is like this.
When practicing HIIT, I didn’t seem to have time to think about anything at all.
