Looking ahead to the off season, I would like to try and build my daughters arm strength up, if you have time to watch the short video...I was wondering if this would be a good idea? Has anyone tried a similar regimen? Also, for those with some experience, do you think great arm strength is mostly genetic or can you build it significantly with hard work?
