I asked this question a couple months ago,I don’t know if it was something you did not want to respond to or it fell through the cracks?I would like my 13 year old grandson to start training this summer.Is there a app or website or coach that offers this service for youths?If y’all have some general programs or guidelines that would be a big help as well?He plays baseball and added strength and athletic ability would go along way towards improving his performance on the field.Thank you Bryce and Joe
