Great article! Interestingly enough, my 2019 just started a long toss program for the 1st time. There's kids in his group from 10-17 yr olds. Everyone is being taught the exact same thing. We meet as a group twice a week for 6 weeks. They want these kids to do Jbands and throw every single day, not necessarily the same amount of throws are same velocity but still throw everyday. We decided on our own to only throw 4 times a week. If I had a younger son in the program I would be concerned that their mechanics could get out of whack while throwing at home, especially if the dad had no clue about mechanics. I guess to each his own, but I wanted my son to start this to build up strength in his arm and shoulder, not to throw harder.
