bb1:
I would guess the standard in most high schools is something along this line.
Throw a 40-50 pitch bull pen either every third day or every other day (some like to throw it every day... I haven't tried that).
Also incorporate long toss on most days.
If you don't have a "game" to throw you would add a 60-pitch pen possibly...
I think most programs go pretty close to these guidelines...
I will say it is hard in HS ball to get all your pens in sometimes due to facility, weather or having a small staff (don't blast me and tell me how important it is... I said it is hard; i didn't say don't do it)
anyway, good luck this spring.
