It was more than just select, strength training, batting and pitching coaches. Select ball isn't much. We were in 18 U since the boy turned 15. The high school does nothing.
His baseball friends are all still stuck in that grind. Summer schedule is 5 lifts a week, three strength training, four batting sessions, two practices and weekend tournaments all over. Ours did pitching also. He still lifts 5 days a week. Gold's, $35/month, nice.
That's not excessive, it's just about the minimum to make the team, unless you are in some way associated with football.
One more addition. They do all that plus stand around three hours three days a week for baseball "practice" and games twice a week. I estimate they spent three full weeks of baseball class sitting in the locker room, from what the kid told me. And probably another three weeks of field work as in weeding the field. I really don't see why anyone does High School baseball, the time requirements are insane.
