Exercise ball at work

MarieAnneN

I was thinking to replace my chair by a 55 cm exercise ball to help workout my chore body while sitting and working at my desk/computer.
Do any of you do this?

Tips?
Tricks?
Advise?

Note: I am 5p9.5, will a 55 cm ball be enough?

I have been using one at work for the last year. Absolutely love it and have switched the one at home now too. Core has never been stronger and all my back pains have disappeared. Good luck.
