Hi everyone,

I am just starting the exercises in the book and wondering what size ball is required. Looking at the pictures the ball Eric uses seems to be level in height to his knee.  The ball I have is quite a bit bigger. Should that matter?

Cheers

Rich

Hey Rich
Every size presents its own challenges, but in general go with this guide:
Under 6ft - 55-65 cm
Over 6ft - 65-75 cm
The amount of air will also affect challenge and difficulty, so play and experiment with that as well.
Thanks for the reply Eric. I think the ball is a 65, so with me being around 5'11" it should be fine.

Cheers

Regarding the amount of air, does more air make it more or less difficult. The ball I am using needs inflating (I can't find the pump adaptor- DOH!) and I really struggle to even start some of the movements.  Obviously some (maybe all) of that will be lack of core strength, but wondering if some of it is down to the deflated ball.

Cheers

Rich

Hey Rich,

In many of the exercises, less air will make it more difficult and challenging.  With more air, you add more stability which will make things a bit easier - across the board.
