how to get strength throwing arm

Question
What is the best exercise for a 7 yrs old kid to get some strength in his trowing arm? We practice 2 or 3 times a weak. is that enough?

Thanks

Answer
Randy,
Don't be concerned about arm strength at this age.  You should be concerned with the proper mechanics and being accurate.  Learning the basic fundamentals of throwing, fielding, hitting, and understanding the game of baseball are most important at your sons age.
