Thanks CoachPaul. That is how I ramp up/work my pitchers during the warmer weather with a couple of bullpens per week. I use 2-4 sets of 5-15 pitches to simulate innings.
For NE winter workouts, I have all the pitchers throw a set of five pitchers and then a couple/three of sets of 10-15. We could get to three of four sets but time limits us as does to goal of having 6-8 kids work on pitching. We have two mounds available.
After three weeks, none of the kids report any arm issues nor do they look as if they are hiding any while telling us coaches what they think we want to hear.
I haven’t typically had kids pitch off flat ground for the reason Mr. Ellis mentions. I am intrigued with the idea of a mound session from a shorter distance to see the kids naturally adapt to getting the ball down.
Have others seen this positive effect?
