Hi Grace
It’s probably a matter of using Google to locate it, or visiting your local sports shop and checking out their stock of mini basketballs.
Here’s what I responded at the Free Techniques Video Section a while back:
I have the ball I normally use right here. I am copying the text on it for you. It is a Nike brand BALLER with Utra-Durable Cover for Outdoor Competition. It is mini-basketball.
I hope you can locate something suitable.
Here’s something important: you need a little give in the ball so it may be too inflated for the exercise when you buy it. So deflate it a little. On the video I show you how ‘soft’ it should be by pressing down on a selection of balls.
Namaste
Gabrielle 🙂
