Don’t be intimidated by Stability Balls. They are a great modality to take your workout up a notch and you’ll increase balance and stability at the same time as working your core. Who doesn’t love multi-tasking in the gym!!??! If you can do over a 2 minute plank, it’s worth going out and buying one of these because you’re wasting time on the floor in ISO prone plank position, when you could be challenging yourself more in the same time, or even half! Trust me, you’ll feel it.

My personal challenge to you — try this today and keep at it for 30 days. Then try it again and see how much strength you’ve gained in your core. I’d take pictures too, if you’re planking every day, there’s going to be some visible changes :)
