Mark Ottobre shows how to do stir the pot on a Swiss ball, rolling it in large circles to challenge your core's anti-rotation. Do it for time, at least 60 seconds, rather than counting reps. You can go one direction then switch, or alternate single reps between sides.
This is Stir the Pot. All you're going to need is a Swiss ball, and you're going to roll it out as far as you can, and you want nice big circles. So stir the pot. There's a few different ways you can do this. You can do all your reps, say for example you go 5 reps one way, then you go 5 reps the other way, or you can do one rep one way and one rep the other day. There's really no wrong or right here, just feel it. Usually this is going to be prescribed for time. I like to prescribe at least 60 seconds. This is Stir the Pot, an anti-rotational exercise. Give it a go.
