We know that using KaioKenKaio-ken damages your body as you are forcing it to go beyond it'sits limits.
But But is it also increasing your potential for the higher power? I mean as the body is facing the forced power up it will try to improve and endure that power the next time, right? I guess it works kinda like muscle training, the more you push your muscles thethe more they develop.
So
So can't Goku stay in the kaiokenKaio-ken mode for an extended amountperiod of time (while not fighting) to increase his capacities and go beyond kaiokenKaio-ken X20?
