Planks on an Exercise Ball

[Veronica]

I read twice and now I'm still asking myself if I maybe didn't understand you right

You KNEEL on a swiss ball, and, if that wasn't enough, you then raise your arms and bend over holding a broomstick in your hands?!

I wish I could balance sitting/lying on a swiss ball for some seconds without doing anything... (I could picture myself doing the above, but the broomstick would need to be a Nimbus 2000... )

I think she's talking about doing hyper extensions on the ball. I did almost all of my upper body work today while standing or squatting isometrically on a Bosu.

Everything except the kettle bell work. Kettle bell swings with 35 pounds - ouch!
