Help my dad improve please
Please help me figure out how I can help him throw further.
Me and my dad have been playing together as a way to bond. He likes the sport a lot but finds himself deeply frustrated that he is not improving on the distance. We will invite other people, which are both his age and body build, who has a natural tendency to throw further from the get go.
I have tried many ways of directing his throw, to increase momentum, spin, etc. but I am struggling to see why it’s not going further or what to tell him. I’ve tried «pouring the vase», reaching further back, bettering g the grip, etc.
His average drive is maybe 40m/130feet.
