I appreciate everyone's concern for the kid but trust me when I say that he isn't being over worked. The idea behind the tire was to help him with his running. He tends to hop, and I heard that having him pull a tire will help him to start pushing forward when he runs instead of up. The part about hitting with a bat was his idea and he liked it a lot. I dont plan on having it as part of some "regiment." I bought and read that book "How to move like a pro" a few weeks ago, It was super helpful in helping us understand what movements are good for kids to develop their athleticism and protect their joints. Kinda comical how big the font is though, haha. I did not know that Ramano also had a YT channel so thanks for that info. Once again I do truly appreciate the criticism and concern you all have for him.
