Okay so ya all seen Iwaizumi arm wrestling with Kyoutani huh

But what if he arm wrestling with his love child

Oh wait... Love children

The older son saw Iwaizumi came back from work and yelled: Arm wrestling me old man!

Iwaizumi: Bring it on kid

Older son calls the younger son and said: both of us will arm wrestling you at the same time

Iwaizumi: whatever just bring it on

Then the older son on the right hand and the younger one of the left

Iwaizumi shouted: YOU LITTLE BRATS ARE 20 YEARS TOO YOUNG TO DEFEAT ME

and both of his sons got defeated

Bonus:
