Do we train our selfs

Do we get senseis or train our selfes

...

you can't train yourself jutsu, no

well thats not really what Cut asked but Cut it depends on what on really i guess.

for example: You have just acquired Lee like ankle weights and want to increase your speed. You then go down to a training ground (topic you have made) and roleplay it out.

when it comes to jutus, no

taijutsu yes you can because taijutsu is regular fighting with no chakra.
