I am a sophomore in high school, topping out at about 84-85.
My goal this offseason is to improve my vertical, have a strong AND explosive core, chest, and arms
Also hope to improve accuracy of all three pitches for next year
So far, I’ve worked extremely hard but not gotten many results, my goal is to throw 90 by next year but I’m not making that good of progress
If anyone has specific workout routines that have worked I’d love to hear 'em
