Pitching routine 11 year old

Whats the recommended routine for 11 year old pitcher? My son usually throws less than 50 pitches a game once and sometimes twice a week. I was told to rest the day after and then throw bull pen session of 30 pitches each day until the next start. Also, what is a good routine in the off season?


After a 50-pitch outing, I would suggest 2-3 days rest, followed by a bullpen, followed by more rest before the next outing. “Rest” means playing catch but no pitching.
