she swings on the average during her lessons twice a week 250-300 swings according to her blast.. and we do our tee work and drills on our own two other nites maybe 150-20 and a hour cage on Sunday. we have two holders that hold 24 balls and we pick up probably 4 -5 times..
That's a lot of swings. I think the most I put 18yo DD through is ~150, and that's in the cage when she's having issues. I was able to get her outside the other day on a ballfield for the first time this year. I cut it short <100 swings because things were going so well that throwing any more pitches was pointless. I think her arms would fall off at 200+ swings.
