Sparring is where two people train together for two days at a time.After two days are up then you take 1/4 of the other persons Power Level,Ki,and experiance points and add them into yours.
Ex:
Goku and Vegeta spar for two days. Goku's status before sparring is.
Power Level:2,500
Ki:125
Experiance:25
Vegeta has the same status. So after they finish their status would be.
