I personally don't believe in the traditional forms of Chi energy. It has a long history entagled with ancient spirituality and mythology. That being said, there is also the medicinal understanding of Chi that lines up surprisingly close to our bodies natural bioelectric flow.

Anyway, I've focused before and been able to feel the blood rushing in my fingers, which feels somewhat like a small electric current. I imagine some people would call this Chi.

Also when you are doing something like Taijiquan push hands, you can develop a sense of the other persons balance and body mechanics, and some on the more mystical side would call that Chi.

Because Ki isn't seen as science it is hard to say how you would feel or harness it. It is hard to say it exists. Many people describe it as a tingling and in my personal experiences it can be created by rubbing your hands together vigorously. To test this theory, find a friend and have them close their eyes and stick their hand out vertically, meanwhile rub your hands together for about a minute. Then hold both your hands on each side of the other participants hand(but don't touch their hand) and move your hands up and down. If their hand moves as you are passing your hands over theirs it could be a sign you have harnessed the ability. Once again however, it is hard to prove that Ki even exists and even with my experiences I am a skeptic. If this ability can be harnessed it will take more than just a one time try to do so. Best of luck.

Power up to Super Saiyan mode

Or you can just accept the fact that life is not an anime and you are not Goku. And maybe...just maybe train something real.

You need to work on cardio , then forms then technique then spiritual wellness.

This is what you're looking for.
